What are the factors that affect the sintering temperature of alumina

 

Aluminum oxide ceramics occupy a large proportion in both domestic ceramics and industrial ceramics, especially in heavy wear and tear fields such as power plants, cement plants, ports, and mines. High purity aluminum oxide ceramics are highly favored, but the melting point of aluminum oxide is as high as 2020 ℃, making sintering extremely difficult. How to reduce the sintering temperature without affecting the performance of aluminum oxide has always been a research topic for many manufacturers,
