2011 Stock Times News Network May 27 evening, CMOC (603993) announcement that rainbow Xiang Luoyang Mining Ltd. v. infringement by company rainbow Cheung Company May 14, 2013 for withdrawal of prosecution, the Luoyang Intermediate Court review, quasi Xufei Hong Xiang withdrew its prosecution. Copper Lead Zinc Tin nickel, China Nonferrous network, a small metal, scrap metal. First instance court costs by the plaintiff company Cheung rainbow burden on CMOC current period profits and other profits or no significant impact. Copper Lead Zinc Tin nickel, China Nonferrous network, a small metal, scrap metal.Partial pressure of the furnace by adjusting the temperature to control the amount of molybdenum chloride, molybdenum furnace, the more the higher the voltage divider. Caolin You said that the use of the technology, they each received a chip size, atomic diameters thick molybdenum sulfide layer film. Also obtained by changing the partial pressure of 2-4 atoms thick Molybdenum crucible sulfide film diameter. Researchers are now trying to find other ways to produce similar but each atomic layer film composed of different materials. Meanwhile, they are also using new technology to produce field-effect transistors and light-emitting diodes.
The thinner the semiconductor thin film, the nano-electronic devices more popular. North Carolina State University, the thickness can be prepared only a single atom diameter semiconductor thin film, the key lies in its choice of materials.the unique layered structure of molybdenum disulfide, molybdenum sulfide layer is a direct band gap, as compared with the conventional silicon material, it is smaller, the dielectric constant is smaller, which means that the transistors than the conventional more power. Thus, a new growth mechanism of molybdenum sulfide appearance can make a single layer molybdenum disulfide has been in the process of preparing methodological weaknesses, and thus open the door to this fan applications.
Molybdenum carbide has a high melting point and hardness, good thermal stability and mechanical stability, and excellent corrosion resistance and other characteristics. Molybdenum is a silvery white refractory metal, a melting point of 2615 ℃, density of 10.2 g / cm 3, the expansion coefficient is small, a special tube is almost the same coefficient of expansion of the glass. Molybdenum stable at room temperature is higher than 600 ℃, rapidly oxidized.
