Preparation and characterization of W–Cu nanopowders by a homogeneous precipitation process

A novel homogeneous precipitation process was employed to prepare nanosized W–Cu powders. Precipitates of CuWO 4·2H 2O and Cu 2(OH) 2WO 4 were first obtained by adding sodium tungstate and copper chloride into aqueous ammonia solution, and then heating the solution to remove ammonia. The precipitate...
