Fly ash generated in coal-fired power plants is produced mainly from the aluminosilicates in coal powder. To utilize fly ash in making refractory products, a study of the synthesis of mullite from fly ash and alumina powder mixture was initiated. A series of sintered products designated M70, M60, M50 was achieved with Al{sub 2}O{sub 3} contents in the mixtures being 70%, 60%, 50%, respectively. Properties of M70 and M60 are comparable to those of commercial mullite. Though the M50 cannot be used as superior refractory material, it has great potential in making ceramic kiln tools to replace the traditional clayey products.
