摘要
There is disclosed a method for preparing a powder containing ammonium salts of W+Co(Ni) complex ions, through chemical reactions, in a water solution at temperatures from 70 DEG C. to the boiling point and at pH around neutral, between tungstate salts and cobalt (nickel) salts characterized in that said tungstate salts are the highly soluble sodium tungstate or ammonium metatungstate.
