Effect of Different Coal-Enrichment Wastes on the Physical and Mechanical Properties and Phase Composition of Heat-Insulation Materials

Resumo

Heat-insulation ceramic materials were obtained on the basis of coal-enrichment wastes: coal-enrichment flotation wastes from Tomusinskaya Ore Mining and Processing Factory (GOF), flotation coal-enrichment slurries (carbon slurries from Obukhovskaya Central Processing Factory (TsOF)), coal-enrichment wastes from Abashevskaya TsOF, and coal-enrichment wastes from Korkinskii razrez using inter-shale clay without conventional native materials. It is shown that anorthite, cristobalite, and hematite are formed at firing temperature of heat-insulation materials 1000°C. Grade A and B heat-insulation brick was obtained.
