Calcined alumina is a high-performance inorganic material prepared by a high-temperature calcination process. It has the characteristics of high specific surface area, porous structure, and high hardness. It is widely used in catalysts, adsorbents, ceramics, refractory materials, electronic devices and other fields.Zibo Xiangrun is committed to the production of various types of calcined alumina.
Product features
Ultra-high purity: Al₂O₃ content ≥ 99%, extremely low impurity content, suitable for high-precision industries (such as electronic ceramics, catalysts).
Chemical inertness: acid and alkali resistant, anti-oxidation, can be used for a long time in harsh environments.
Thermal stability: does not decompose at high temperatures, suitable for applications such as refractory materials and high-temperature coatings.
