The fly ash from powerplant can be compared, due to its genesis, chemical and mineralogical composition with the natural volcanic glasses and minerals generated in the process of devitrification in situ. Its quality is comparable to non-metallic alumosilicate raw materials that are commercially used in building and ceramic industry. Two possibilities of fly ash utilization as the most bulk waste produced by anthropogenic activity were examined. The way of fly ashes utilization in the modeling of mixtures for the high refractory mullite corundum materials synthesis was examined. In this experiment 95.5% conversion of the input components of fly ash and Al additive in the ratio 1:1 on the mullite and corundum was obtained.
