METHOD OF PRODUCING FINE TUNGSTEN CARBIDE POWDER

摘要

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.;2 ex
