Research Review of Sialon Based Refractories Prepared from Industrial Solid Wastes with High Alumina in China

摘要

Industrial solid wastes with high alumina,such as fly ash,coal gangue and blast furnace slag and aluminum dross,may be good raw materials to prepare bargain Sialon matrix refractories.Based on our previously studies,this paper reviewed the research of Sialon matrix refractories prepared from Chinese industrial solid wastes,and presented the development tendency,including optimization of impurities,preparation of single-phase Sialon by controlling synchronous reaction and strengthening industrial production and application.
