Diopside based ceramics and glassceramics have potential appliions in various technological areas. A diopside based glassceramic named ''silceram'' was produced by scientists from Imperial College, UK during the 1980s from blast furnace slag and other waste products. They also produced glassceramic is a potential structural material.
