  • Sillimanite refractories cut into various shapes and sizes or made out of bonded particles are used in industries like cement, ceramics, glass-making, metal smelting, refinery and treatment, tar distillation, coal carbonization, chemicals manufacture, and iron foundries.
  • It is very resistant to glass slag and hence widely used as lining material in glass melting furnace.
  • Iron corrodes it rapidly hence it is not suitable in iron smelting.
  • It is also not highly resistant to molten metallic oxides and, therefore, rather unsuitable for metallurgical operations.
