In this paper,the preparation technology and characteristics of aluminosilicate  refractory are reviewed.The synthesis routes of aluminosilicate refractory are mainly as follows:firstly,this kind of refractory can be made by firing clay (mixture of kaolin,clay and alumina);secendly,it can be made from mineral of sillimanite group and bauxite;thirdly,it can also be made from sol-gel synthesis,solid waste containing aluminum,slate,aluminum mud,ceramic waste and so on.The properties of the refractory prepared by these processes are described in detail.
