Alumina is categorized into two types: high-purity alumina (with an Al₂O₃ content exceeding 99.7%) and standard-grade alumina (which, depending on the Al₂O₃ content, is further divided into grades such as 99 porcelain, 95 porcelain, 90 porcelain, and 85 porcelain). Due to its excellent properties—including chemical corrosion resistance, high strength, and long service life—alumina ceramic products are widely used in fields such as mechanical manufacturing, the chemical industry, and electronic technology.

1. Product Performance

· High-temperature resistance

Capable of withstanding extremely high temperatures (typically above 1600°C), making it suitable for processes such as high-temperature melting, chemical reactions, or material sintering.

· Thermal shock stability

It can effectively resist cracking or damage caused by temperature changes during rapid heating or cooling.

· Thermal conductivity

It has excellent thermal conductivity, enabling uniform heat transfer and making it ideal for experiments or production processes that require precise temperature control.
