Abstract
The paper presents research results on silicate melt and glass-ceramic material production based on ashes generated by thermal power plants using the energy of thermal plasma. A plasma-chemical reactor is designed and tested. Calculations show that when the thermal power of plasma torch varies from 50 to 100 kW and the optimum melt temperature of 1850 °C is maintained in the plasma-chemical reactor, the feed rate varies. The dependence between the crystallization properties of the melt and the mixture composition is established. To obtain the material with increased crystallinity, the resulting silicate melt is subjected to plasma treatment at 700 °C for 1 hour and 950 °C for 2 hours. The degree of crystallinity increases up to 60–65 %. Compressive and flexure strength and coefficient of linear expansion of obtained products are determined. The obtained results are compared with those available in the domestic and foreign markets.
