METHOD OF PRODUCING FINE TUNGSTEN CARBIDE POWDER Russian patent published in 2012 - IPC C22C1/05 B22F9/18 

Abstract RU 2452784 C1

FIELD: metallurgy.

SUBSTANCE: proposed method comprises magnesium reduction of tungsten oxide and carbon oxide (CO2) in medium of the melt of lithium carbonate (Li2CO3) at 800-900°C with tungsten oxide-to-lithium carbonate ratio of 1:5-7, and separation of carbide solid phase from the melt.

EFFECT: reduced smelting temperature in single-step process.
