Classification of refractory materials based on fusion temperature

- Jun 14, 2018-

Based on fusion temperature, (melting point) refractory materials are classified into three types.

  • Normal refractory: fusion temperature of 1580 ~ 1780 °C (e.g. Fire clay)

  • High refractory: fusion temperature of 1780 ~ 2000 °C (e.g. Chromite)

  • Super refractory: fusion temperature of > 2000 °C (e.g. Zirconia)
