Results of the study of sintering possibility of an ash-liquid glass composition produced on the basis of ash of the Thermal Power Station-2 of Kazan, consisting of 70% of glass phase and 15% of amorphous phase and ash of the Novo-Irkutsk TPP with 44% 0f crystal phase and 56% of amorphous phase are presented. Ashes consist of hollow vitrified spheres and contain minerals which are part of the burned ceramic material, quartz and mullite first of all. On the basis of samples produced by pressing from the powder on the basis of ash and liquid glass, results of the comparative analysis of strength of samples after heat treatment in the muffle furnace according to the traditional burning in the ceramic technology up to 1000°C and heat treatment under conditions of microwave heating in the electric field of ultra-high frequency are shown. Samples past irradiation in the ultra-high frequency field have shown greater strength comparing with the sample after conventional thermal heating. The structure of the sintered material and differences in color of the samples of thermal roasting and heating in the UHF furnace are shown. On the basis of the early conducted study of the effect of UHF field on the alumo-silicate compositions taking into account the difference in content of the active amorphous phase part in the ash and differences in strength indicators, it is assumed that the alumo-silicate structure of (share of crystal and amorphous phases) impacts on its reaction ability during the sintering process.
