Preparation Technology and Research Progress of High-Purity Molybdenum Powder
With the fine development of the electronics industry,high purity molybdenum is widely used in the elec-tronics industry because of its small film stress,good high temperature stability,good electrical conductivity and low impedance.This paper systematically summarizes the preparation technology of high purity molybdenum pow-der,including:clean reduction decomposition technology of high purity molybdenum raw materials(ammonium mo-lybdate,MoO3,MoCl5,Mo(CO)6,MoS3,etc.),ordinary molybdenum powder electron beam melting and plasma spheroidization purification technology.Precipitation method,solvent extraction method,ion exchange method and crystallization method to improve the purity of ammonium molybdate are emphatically discussed.The advantages and disadvantages of different purification methods were pointed out.The preparation technology and application prospect of high purity molybdenum powder were summarized and discussed.
