摘要：

Previous research in the field of preparing SiC-containing suspensions, and also refractory materials based on them, are analyzed. The effect of SiC additive fineness in composite HCBS of the Al2O3-SiO2-SiC system is studied with a predominantly high-alumina composition on the properties of materials based upon them after firing the range 1000 - 1400 degrees C. The effect of firing temperature on specimen shrinkage and growth, and their porosity and strength in bending are studied. For specimens after firing at 1200, 1300, and 1400 degrees C a weight increase is detected pointing to SiC oxidation with formation of SiO2. The maximum ultimate strength in bending (110 - 130 MPa) is achieved with a firing temperature of 1200 degrees C, and the ultimate strength in compression for specimens of all compositions after firing at 1200 degrees C is 200 - 425 MPa.
