As the temperature increases, content of quartz, anhydrite, and hematite in coal ash decrease in reducing conditions and some new mineral phases are formed during heating process. The content of mullite formed in the heating process is the mayor reason of high melting temperature of the ash. Anorthite at high temperature lowers the ash fusion temperature.
