The development and production of Al2O3 porcelain originated in Germany. Since then, major American companies have successively developed various Al2O3 ceramics. In the field of research, they consider ceramic and metallization technologies together, so that the two can be better matched and adapted.

Alumina ceramic tubes have a wide range of applications, involving high temperature testing and analysis equipment in various industries, such as coal testing and analysis equipment, metallurgical powder testing and analysis equipment, chemical and glass industry testing and analysis equipment, etc.
