METHOD OF PREPARING MULTICARBIDE POWDERS FOR HARD MATERIALS

There is now provided a method for preparing a powder containing W and Co and/or Ni from APT and a soluble salt of Co(Ni) by a chemical reaction in a water suspension at temperatures from room temperature to the boiling point of the solution whereafter the formed powder is filtered off, dried and re...

description	There is now provided a method for preparing a powder containing W and Co and/or Ni from APT and a soluble salt of Co(Ni) by a chemical reaction in a water suspension at temperatures from room temperature to the boiling point of the solution whereafter the formed powder is filtered off, dried and reduced to a metallic powder. Additional metals from groups IVa, Va or VIa of the periodic table of the elements are added to the suspension as compounds like oxides, hydroxides, soluble or insoluble salts.
