Refractories and Industrial Ceramics Aims and scope

Abstract

Synthesis and properties of fusion-cast high-alumina refractories in the Al2O3 – B2O3 system are reported. Adding B2O3 is shown to improve density and fabricability of the fusion-cast products. As shown by x-ray diffractometry and petrographic analysis, the phase composition of synthetic products is represented by corundum and 9Al2O3 ċ 2B2O3 boroaluminate. Corrosion tests in molten industrial glasses have shown the potential use of these materials in the melting technology of VS-92-grade optical lead silicate glass.
