FIELD: ceramics. SUBSTANCE: raw meal is composed of, wt %: microsilica from crystalline silicon production 70.5-72.5, liquid glass 20.5-22.5, and fired clays 7.0. Microsilica is mixed with glieges and then liquid glass is added. Resulting mix is molded using fry compaction technique to form samples, which are fires at 650-700 C. Thus obtained material is characterized by average density 1200-1280 kg/qu.m, compaction strength 35.5-39.8 MPa, and water absorption 42.5-43.8%. EFFECT: increased compaction strength and constructive quality factor. 2 tbl _ |
