Difficulty preparing large-grained molybdenum powder mainly 3:00: large size, high density, good liquidity. Satisfy the requirements of this 3:00 molybdenum powder morphology is the ideal large diameter solid sphere, which is a non-conventional molybdenum powder particle size loose group of different morphologies. In general, increased molybdenum powder reshaping technology are mainly two types of chemical and physical methods. Now briefly introduced large-grained molybdenum powder preparation techniques of chemical technology . 

 

Preparation of a bulk single crystal particles of large particle size of ammonium molybdate, a genetic principle, by a subsequent calcination, reduction, to prepare the large particle size of the molybdenum powder true particle (actually a conventional molybdenum powder particles aggregates of many small particles), and then certain mechanical treatment to obtain a rounded morphology, density, large size of the molybdenum powder particles. This method is theoretically feasible, but the difficulty of preparing large single crystals of ammonium molybdate larger particles, and the subsequent rule of hereditary molybdenum powder to quantify the size and morphology is not clear, the process is longer.
