The in6uence of the composition of a carburizing CH 4 +H 2 gas mixture on the process of reduction+carburization over WO 3 has been studied. Bulk tungsten carbide synthesis has been carried out from WO 3 in di4erent CH 4 +H 2 mixtures (CH 4 +H 2 ‫؍‬ 1/1+3/1; CH 4 +N 2 ‫؍‬ 1/1; pure CH 4 ) at atmosph
