Mullite has many excellent physical and chemical properties because of its unique crystal structure and composition,and is widely used in the preparation of composite materials.The application of mullite in coating material,polymer material,thermal energy storage material,wave transparent material,thermal insulation material and ceramic membrane material were reviewed.It was pointed out that the study of mullite based electrical and optical materials should be strengthened on the basis of existing research.It was necessary to develop appropriate technology to purify mullite phase in high alumina fly ash,and applied it to appropriate composite materials,so as to realize the consumption of fly ash solid waste and the utilization of mullite resources.
