[en] Tungsten carbide is widely used in the production of cutting tools and parts with very good
resistance to wear. It is well known that the properties of sintered carbides are closely related
to the carbide particles size. Tungsten carbide production is a laborious process, which always
includes a milling step. This article aims to study the manufacturing of tungsten carbide by
carburizing tungsten trioxide using mechanical alloying (MA) method, thus concentrating the
process in one step. Experimental tests were performed with a Fritch planetary mill and
complete conversion of tungsten trioxide in carbide was observed after 30 hours of milling.
The average value of D50 for the synthetized WC is 6.73 0.62 μm.
