The reduction and carburization behavior of NiO–WO 3 mixtures by CO was studied using thermogravimetric and differential thermal analysis techniques (TGA–DTA) with the aim of preparing homogenous Ni–WC composite powders. Based on the TGA–DTA results and characterization of the reaction products using XRD and SEM, the following reaction path is suggested. Reduction of NiO with CO begins at...
