Title: Fabrication of ultrafine tungsten-based alloy powders by novel soda reduction process

Abstract

A novel reduction method has been developed to fabricate ultrafine tungsten heavy alloy powders, with ammonium metatungstate (AMT), iron(II) chloride tetrahydrate (FeCl{sub 2}.4H{sub 2}O), nickel(II) chloride hexahydrate (NiCl{sub 2}.6H{sub 2}O) as source materials and sodium tungstate dihydrate (Na{sub 2}WO{sub 4}.2H{sub 2}O) as a reductant. In the preparation of mixtures the amounts of the source components were chosen so as to obtain alloy of 93W-5Ni-2Fe composition (wt.%). The obtained powders were characterized by X-ray diffraction, XPS, field-emission scanning microscope (FESEM), and chemical composition was analyzed by EDX.
