Research on Preparation Process of Ultra-coarse Grained WC Powder AITranslate
Abstract AITranslate
The process was investigated of capping reduction-high temperature carbonization to prepare ultra-coarse grained WC powder.WO_3 is put into a special boat for hydrogen reduction at 930～980 ℃ at first and then carbonization at 2 300℃.Compared with the two processes of traditional medium temperature reduction-high temperature carbonization and doping reduction-high temperature carbonization,the process of capping reduction-high temperature carbonization can produce ultra-coarse grained WC powder with fuller particles,coarser grain size,more uniform particle size distribution and more complete crystal.WC powder prepared by this process has abrasive grain size of 7.4μm,reaching the requirement of ultra-coarse grained WC for grain size.
