Cellular Heat Insulation Building Glass Materials Based on Wastes from Thermal Power Plants and Ferrous Metallurgy

Resumo

The physical-chemical processes involved in the formation of the cellular structure of heat-insulation building glass materials as a result of thermoplastic sintering of batch at temperatures 600 – 870°C are examined. Such a cellular glass formation process occurs because the significant gas-phase volume formed at low viscosity diffuses in the thermoplastic ceramic mass and in so doing creates the pore structure of the cellular heat-insulation glass.
