METHOD OF PRODUCING CHROME BORIDE POWDER Russian patent published in 1995 - IPC

Abstract RU 2048975 C1

FIELD: metallurgy. SUBSTANCE: process of chrome boride smelting in ore-thermic electric furnace is carried out using the charge in which the ratio of diboron trioxide to chrome sesquioxide is 0.46-0.8, and the ratio of carbon to the total content of boron and chrome oxides is 0.41-0.55. Method provides producing monophase solid liquid boron-chrome. EFFECT: improved method of chrome boride producing. 3 tbl
