1. Good high temperature resistance.The performance of refractory raw materials in high temperature environment is stable, there will be no rapid expansion or contraction, and the service life is long.2. Good cold and heat cycle resistance.Refractory raw materials have good thermal stability and will not cause cracks and damage due to temperature changes.3. Excellent wear resistance.Refractory raw materials have excellent wear resistance and can be used for a long time at high temperatures.4. Good corrosion resistance.Refractory raw materials are less corrosive to acids, alkalis and other chemicals, and can be used for a long time in complex chemical environments.5. The structure is dense.Refractory raw materials have high density, dense structure, and are not easily eroded.
