Аннотация
HCBS of composite composition are prepared by combined wet grinding using fuzed corundum-bauxite containing 93.4% Al2O3 (45%) and sintered Chinese bauxite (45%) as basic materials. The additional component within the composition of the milling charge is very fine quartz glass (10%). The effect of firing temperature in the range 900 – 1600°C on material sintering and mullitization is studied. Values of ultimate strength in bending of 150 MPa are achieved after firing specimens at 1200°C. The material sintering (shrinkage) and mullitization temperature ranges are established.
