Historic low molybdenum time to get rid of winter yet
recent years, the domestic molybdenum prices have ups and downs, but the overall price trend concussion. Since the 2008 global financial crisis, molybdenum prices low DECADE. As of the 16th, the domestic content of 45% molybdenum's latest offer is about 1400 yuan / ton level, when compared with the beginning dropped by about 10 percent, fell in August 2012 historic low levels, compared with 2005 high shrink about 80 %. According to the Shanghai Metals Market (SMM) research to understand, from mid-2012 onwards, Shaanxi, Henan, Liaoning and other companies have discontinued the main producing molybdenum insured, but the actual effect is very unsatisfactory and only in December 2012 to 2013 February, the market price due to supply reduction and steel procurement and rebound. At present, the Shaanxi region has ore mining scale enterprises can be molybdenum (content 45%) of production costs at 1500 yuan / ton degrees nearby, and some small businesses, low-grade ore, production costs at 1600 yuan / t degrees. Below the cost line of the grim situation to make the industry initiative to stop the resurgence of the wind.
Insiders believe that the leading precious metals price trends of the industry supply and demand pattern. Prolonged downturn in the domestic steel industry in recent years, steel mills bidding prices down, as the charge of molybdenum plating steel product prices spread to the upstream industry chain, also involving molybdenum prices continue downward. Looking ahead, molybdenum prices have fallen below the cost, but not to force the end demand, despite the supply reduction, but still difficult to translate into significant support price, it seems sluggish performance or molybdenum prices this winter will continue to

Add artificial edge that allows atomic layer of molybdenum disulfide neat
Add artificial edge that allows atomic layer of molybdenum disulfide neat growth China Technology Daily News According to physicist organizational networks reported recently, Rice University and Oak Ridge National Laboratory (ORNL) developed in collaboration with scientists a new method that can control the molybdenum disulfide (MDS) consistently neat atomic layer growth, to manufacture two-dimensional electronic device toward a step forward. Research published this week in the "natural. Materials Science" magazine.
Molybdenum disulfide is a semiconductor Molybdenum tube functional components are required for two-dimensional electron in one of the three materials, they are expected to be made invisible devices based components. In the latest study, the scientists hope to figure out a large and high-quality atom thick sheet of molybdenum disulfide Can the chemical vapor deposition (CVD) furnaces grow and what features they have. They want molybdenum disulfide with no band gap of graphene and hexagonal boron nitride insulator (hBN) binding, thereby making appearances effect transistor logic integrated circuits, photodetectors and flexible optoelectronic devices.
Last year, Rice University mechanical engineering and materials science professor Lou jun (transliteration) and Plymouth Kerr? Ajayan said they successfully produced graphene and hexagonal boron nitride formed complex staggered structure, but in order to use they manufacture of advanced electronic equipment, also need a third material - molybdenum disulfide. . However, they said: "The will of molybdenum disulfide and carbon atoms together, we want graphene and molybdenum disulfide (with hexagonal boron nitride) combine to create a novel two-dimensional semiconductor parts, but because of their different structures , growth environment is different, so there are a lot of difficulties.

Mechanical characteristics
Molybdenum and molybdenum alloys due to its excellent mechanical and chemical properties in the manufacturing sector has been widely used.
Mechanical characteristics:
Molybdenum has excellent properties: melting point, high creep resistance and low thermal expansion and so on. Generated by the addition of other metals molybdenum alloy, these performance has been significantly strengthened. According to the user's application environment and operating temperature, Lighthouse Group can provide to the user the most suitable pure Molybdenum crucible or molybdenum alloy.
Chemical characterization:
Atmosphere without oxygen, molybdenum variety of acids, liquid metal and the molten glass has a very good resistance to corrosion. At 1100 ° C or less, Mo in hydrogen, nitrogen, ammonia and relatively stable molybdenum and steel welding a) molybdenum and steel welding - brazing molybdenum and steel (carbon steel, stainless steel) using welding, electron beam welding and gas welding and other welding methods, welding can be achieved - brazed joints. This welding process is the essence of the steel side of the molten metal more, and molybdenum increase the side just heating without melting or melting little liquid metal is steel formed by infiltration brazed seam. This avoids the formation of iron and molybdenum compounds Fe3 Mo2 and FeMo, the joint area embrittlement problem is solved. Molybdenum steel electron beam butt welding directly, the weld metal composition mainly 20Mo-80Fe in the Mo base material is displayed on the side of the boundary eutectic α + ε, and the formation of large intermetallic Fe3 Mo2 and FeMo. Since the presence of intermetallic compounds, the weld metal brittle and easily cracks increases, reducing the performance of the joint, its poor weldability. Therefore, molybdenum and steel fusion welding, the joint strength is not high, you should avoid direct welding, it is generally used welding - brazing.
transparent and frosted bulb two kinds of different specifications
In 1959 it was discovered after the halogen cycle principle produce halogen, it gives thermal radiation source has injected new vitality, this kind of light, small size, light maintenance rate of 95% or more, the luminous efficiency and lifetime were significantly better than incandescent lamps. In recent years, it has produced can be directly applied to the grid voltage 220V or 110V halogen lamps, and its size can be as small ?14 × 54mm, with a filament stability and shock resistance are excellent characteristics, transparent and frosted bulb two kinds of different specifications, internal fuse in line with IEC A32-2 standard, G9 type lamp is easy to join, its main technical parameters are shown in Table 1 below. In recent years has launched a variety of energy-saving halogen lamps new varieties, such as on the use of quartz foam shell coated TiO2 / SiO2 infrared reflective layer technology (IRC) made JD-and JDR Halogen type novel, by allowing visible light Tungsten eletrode, and the process of the infrared reflecting back to the filament, the lamp luminous efficacy of 30% -45% increase, the life of 3000h. Since halogen chromogenic particularly good, but small volume and easy decoration, so much people still favored and widely used.

As the bubble wall temperature is high enough (250 o C),
What is a halogen tube? Halogen (halogen lamp) is part of the filling gas containing a halogen element or a halide of a pneumatic incandescent lamps. In the ordinary incandescent lamp, the filament of the high temperature caused evaporation of tungsten evaporated tungsten deposited on the envelope, the lamp bulb blackening phenomenon generated. In 1959, the invention of halogen, halogen cycle using the principle of eliminating the black phenomenon.
Halogen cycle process is this: in the appropriate temperature conditions, tungsten wire evaporates from the filament in the area of ??cell wall material react with a halogen, a halogen to form volatile compounds. As the bubble wall temperature is high enough (250 o C), gaseous halogen compounds, halogen compounds when spread to the area around the hotter filament and tungsten halogen Shiyou differentiation. Released to return to the tungsten filament, and continue to participate in the halogen cycle. Fluorine, chlorine, bromine, iodine, can produce a variety of tungsten halogen regenerative cycle. The main difference between them is the desired temperature cycling reaction occurs along with other substances within the lamp with varying degrees of action now mass production of various bromine tungsten lamp and pad tungsten lights, some lights are also part of the use chlorine as a loop agent. In order to make the resulting halide lamp wall in a gaseous state, halogen wall temperature is much higher than ordinary incandescent lamp. Accordingly, tungsten halogen bulb sizes will be much smaller, you must use high-temperature quartz glass or hard glass. As bulb size, high strength, light allowed on the high pressure, high temperature combined, the operating pressure within the lamp is much higher than ordinary light bulb inflator. Since the evaporation of tungsten halogen being more potent inhibition, while halogen cycle eliminates the bubble shell black, filament temperature and luminous efficiency can be greatly improved, and the lamp life can be extended accordingly. Divided into the main voltage halogen halogen (220V-240V direct access to power) and low-voltage halogen lamps (to be equipped with the appropriate adapter) are two low-voltage halogen lamps have a relatively longer life, safety performance lamps advantages. Choose halogen tips: color temperature of light, life, security, and whether filters to remove ultraviolet light.
Halogen cycle process is this: in the appropriate temperature conditions, tungsten wire evaporates from the filament in the area of ??cell wall material react with a halogen, a halogen to form volatile compounds. As the bubble wall temperature is high enough (250 o C), gaseous halogen compounds, halogen compounds when spread to the area around the hotter filament and tungsten halogen Shiyou differentiation. Released to return to the tungsten filament, and continue to participate in the halogen cycle. Fluorine, chlorine, bromine, iodine, can produce a variety of tungsten halogen regenerative cycle. The main difference between them is the desired temperature cycling reaction occurs along with other substances within the lamp with varying degrees of action now mass production of various bromine tungsten lamp and pad tungsten lights, some lights are also part of the use chlorine as a loop agent. In order to make the resulting halide lamp wall in a gaseous state, halogen wall temperature is much higher than ordinary incandescent lamp.
