Is it necessary to use Australian alumina powder in the production of tabular alumina

It is not necessary to use Australian alumina powder in the production of tabular alumina.

Australian alumina powder is commonly used in tabular alumina production due to its advantages such as high alumina content, low impurity content, and stable chemical composition. However, domestic alumina powder also has certain competitiveness. Although the impurity content of domestic alumina powder, such as Fe₂O₃, SiO₂, and Na₂O, is slightly higher than that of imported powder, the alumina content is not significantly different. Through scientific proportioning, tabular alumina produced from a combination of domestic and imported powder can also meet performance standards and usage requirements.

In addition, some domestic companies have broken the situation where imported alumina raw materials were previously the only option for producing tabular alumina. For example, Chinalco Shandong New Materials Co., Ltd. has become the first enterprise in China to produce tabular alumina using domestic alumina raw materials by precisely controlling key parameters and strictly monitoring various technical indicators in the production process.
