METHOD OF PREPARING CORUNDUM CERAMIC MATERIAL Russian patent published in 2001 - IPC

Abstract RU 2171244 C1

FIELD: manufacture of products from constructional ceramic material, more particularly wear- and chemically- resistant equipment components that withstand high static loads. SUBSTANCE: in order to prepare blend of corundum ceramic material with lower sintering temperature of 1450 C, method comprises using aluminium hydroxide or alumina calculated for aluminium oxide (88-92 wt %) which is mixed with mineralize glass additive presintered at 900-1000 C. Glass additive comprises MgO, CaO, SiO₂,B₂O₃ at 0.5:0.5:1:1 weight ratio. EFFECT: lower sintering temperature with main strength characteristics unchanged of constructional corundum ceramic material. 2 tbl
