With the increasingly development of automobile, electronics, aviation, spaceflight and other industries, it has put forward higher and higher requirements on the quality of molybdenum powder metallurgy products. Therefore, it is required that molybdenum powder should have better performance in chemical composition, physical morphology, average particle size, particle size distribution, apparen...
Black shale ore contains rich strategic metal resources such as vanadium, nickel, and molybdenum, but due to its complex composition, it is currently only used in the vanadium extraction industry. Metals nickel molybdenum have not been effectively recovered, resulting environmental pollution resource waste. Using mineralogical features a combination of beneficiation metallurgy-based tests, pres...

The need for structural materials with high-temperature strength and oxidation resistance coupled with adequate lower-temperature toughness for potential use at temperatures above ,1000 8C has remained a persistent challenge in materials science. In this work, one promising class of intermetallic alloys is examined, namely, boron-containing molybdenum silicides, with compositions in the range M...
