Preparation of WC Powder Containing Yttrium by Co-precipitation AITranslate
Abstract AITranslate
The process of doping yttrium by co-precipitation with yttrium nitrate aqueous solution added during evaporation crystallization of ammonium tungstate was studied. Yttrium-doped ammonium paratungstate powder was prepared by the above process,and then tungsten carbide powder containing yttrium was prepared by redox,carbon distribution and carbonization.The results show that yttrium in APT pow der prepared by co-precipitation has relatively uniform distribution, and exists mainly in the form of Y(OH)3. The average particle sizes of tungsten carbide powders doped with 0.5%Y and 1%Y is 0.37μm and 0. 28μm,respectively.Yttrium doping has the effect of refining tungsten carbide powder.
