Abstract
The invention relates to a process for manufacturing a pore free powder metallurgical alloy article starting with a minor portion of Sn powder and a major portion of In.sub.2 O.sub.3 powder and comprising the steps of: substantially uniformly distributing and fixing the Sn powder on the surface of the In.sub.2 O.sub.3 powder by mixing and milling the powders in the presence of a process controlling agent such as an alcohol to form alloyed powders, and compacting the so alloyed powders at high temperature to form the article. The article has a good electrical conductivity and is usable as a target for plasma sputtering ITO compositions.
