CHARGE FOR PREPARING PERICLASE-SPINELLIDE REFRACTORY ARTICLE Russian patent published in 1995 - IPC

Abstract SU 1692113 A1

FIELD: refractory materials. SUBSTANCE: charge has, wt.-% periclase 40-85, and spinellide-containing component containing, vol. chrompicotite at refraction index N 2.00-2.09 85-90; periclase with inclusions of secondary spinellide at the ratio (93-96):(7-4) 7-11; silicates 1-6, and metallic phase 1-2. Properties of prepared refractory materials: onset point of softening under loading 0,2 H/mm2 is 1710-1720 C; thermal stability (1300 C, water) is 17-23 heat exchanges; wear of refractory materials is 1.5-2.0 mm/combustion x hr. EFFECT: increased wear resistance and thermal stability, decreased plastic deformation rate and toxicity. 1 dwg, 2 tbl
