Aluminosilicate Refractories Based on High-Alumina HCBS.

Aluminosilicate Refractories Based on High-Alumina HCBS. Ceramic concrete specimens are prepared based on HCBS of mullite-silica composition (58% Al2O3) and fillers of similar and chamotte compositions, having markedly better properties than for traditional refractories with the same Al2O3 content. An ultimate strength in compression of 150 – 250 MPa with porosity of 6 – 11%, and a temperature for deformation under load T g of 1540 and 1460 MPa are obtained correspondingly for ceramic concrete specimens with an Al2O3 content of 58 and 42%. With respect to T g, mullite-silica ceramic concretes (58% Al2O3) correspond to traditional mullite (62 – 72% Al2O3), chamotte (42% Al2O3) and mullite-silica (45 – 62% Al2O3) refractories. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Refractories and Industrial Ceramics Springer Journals

Abstract

Ceramic concrete specimens are prepared based on HCBS of mullite-silica composition (58% Al2O3) and fillers of similar and chamotte compositions, having markedly better properties than for traditional refractories with the same Al2O3 content. An ultimate strength in compression of 150 – 250 MPa with porosity of 6 – 11%, and a temperature for deformation under load T g of 1540 and 1460 MPa are obtained correspondingly for ceramic concrete specimens with an Al2O3 content of 58 and 42%. With respect to T g, mullite-silica ceramic concretes (58% Al2O3) correspond to traditional mullite (62 – 72% Al2O3), chamotte (42% Al2O3) and mullite-silica (45 – 62% Al2O3) refractories.
