本发明是关于在仲钨酸铵中添加氯化铵、溴化铵和氟化铵(一种或二种以上)粉末,并在氢气中加热还原制备微细钨粉的方法。目前,钨粉通常是通过仲钨酸铵或者氧化钨(WO_3)在氢气中还原制得的。在实验
The present invention relates to a method for preparing fine tungsten powder by adding ammonium chloride, ammonium bromide and ammonium fluoride (one or two or more) powders into ammonium paratungstate and reducing the mixture by heating and reducing in hydrogen. At present, tungsten powder is usually prepared by reduction of ammonium paratungstate or tungsten oxide (WO_3) in hydrogen. In experiment
