Types of refractory materials

There are many types of refractories, which are usually divided into ordinary refractories (1580~1770 °C), advanced refractories (1770~2000 °C) and special refractories (above 2000 °C) according to the level of refractoriness; According to chemical properties, it is divided into acid refractories, neutral refractories and alkaline refractories. In addition, there are refractories for special occasions.

The definition of refractory is no longer limited to whether the refractory is above 1580°C. At present, refractories generally refer to inorganic non-metallic materials used in the lining of metallurgy, petrochemical, cement, ceramics and other production equipment.
