Abstract:
There was obtained the equilibrium phase composition for systems of mullite-sodium carbonate-calcium carbonate, sillimanite-sodium carbonate-calcium carbonate, ash-sodium carbonate-calcium carbonate at different variations of relations of Na2O/Al2O3, CaO/SiO2, CaO/Al2O3. The optimal temperature range for the interaction of aluminous ashes with carbonates was determined.
