Molybdenum market quotation in China: ferro molybdenum, molybdenum oxide and molybdenum powder prices maintain stability in the first trading day on February 1, 2021 with the approaching of Spring Festival.

At present, some molybdenum chemical companies have entered the holiday state ahead of schedule, but due to production costs and the support of some companies maintaining just-needed purchases, suppliers are basically less willing to reduce price, and the market may maintain a narrow consolidation pattern in the short term.

China’s steel industry PMI was 44.3% in January, a decrease of 1.5 percentage points from the previous month, and the operation of the steel industry declined slightly, according to the data released by the China IOT Iron and Steel Logistics Professional cemented carbide blade Committee. The sub-indices showed that the domestic steel new order index was 35.0%, a month-on-month decrease of 7.0%; while the steel new export order index was 55.2%, a month-on-month increase of 0.8%.

A magnetoresistive material is added with a magnetic field, eccentric drill bits whose resistance will change, which is a technically useful phenomenon, such as the utilization in sensors to read data of hard disk. Mazhar Ali and his colleagues now identify a kind of material (tungsten telluride), in which the magnetoresistance effect is abnormally Well Drilling Bits large: the resistance can be changed by more than 13 million percent. Its remarkable reluctance will be displayed in very high magnetic fields and very low temperatures, so the actual application is currently impossible. But the discovery proposed new direction for study on the magnetoresistance, which may eventually lead to new applications of this effect. Tungsten(IV) telluride (WTe2) is an inorganic semimetallic chemical compound. In October 2014, tungsten ditelluride was discovered to exhibit an extremely large magnetoresistance: 13 million percent with no known saturation point. The resistance is proportional to the square of the magnetic field. This may be due to the materiel being the first example of a compensated semimetal, in which the number of mobile holes is the same as the number of electrons. The structure of tungsten concentric drill bits ditelluride is layered, and the substance can be exfoliated into thin sheets down to monolayers. However electrons can easily move between the layers, unlike in other two dimensional semiconductors. The fraction of charge carriers is 0.005 per formula unit (WTe2). When subjected to pressure, the magnetoresistance effect in WTe2 is reduced. At a pressure of 10.5 GPa magnetoresistance disappears. Above this same pressure of 10.5 GPa tungsten ditelluride can become a superconducter. At 13.0 GPa the transition to superconductivity happens below 6.5K. WTe2 was also recently predicted to be a Weyl semimetal and, in particular, to be the first example of a "Type II" Weyl semimetal, where the Weyl nodes exist at the intersection of the electron and hole pockets.http://philipjere.mee.nu/carbide_tool_gradually_squeezing_domestic_high
