Pressure-molded high-alumina ceramic castables. 2. Compaction and properties of materials based on plasticized bauxite HCBS, reactive alumina, and their binary mixtures

Abstract

The effect of compacting pressure (20–100 MPa) on the densification of refractory clay plasticized molding mixes based on bauxite HCBS containing 10% highly dispersed quartz glass, reactive STS-30 alumina, and their binary compositions has been studied. The properties of these materials subjected to heat treatment are discussed. Optimum compositions for binary systems are formulated that show promise as matrices for refractory materials and for preparation of engineering ceramics.
