CHARGE FOR PREPARING CAST CHROMIUM CARBIDE Russian patent published in 1994 - IPC

Abstract RU 2013369 C1

FIELD: manufacture of high-melting products. SUBSTANCE: a charge is prepared by mixing 65-67 wt % chromium oxides containing 35-45 wt % oxygen present therein, 24-28 wt % aluminium and 7-9 wt % graphite. The charge is placed into a reactor and a combustion reaction is initiated. The lower limit of shock sensitivity of the charge is 750-900 and the hygroscopicity of the charge is 0.009-0.025 wt/p. Chromium carbide is a single phase product having Cbind of 13.1-13.2 wt % . EFFECT: improved properties of the charge. 1 tbl
