What is alumina ?

Industrial alumina is prepared from bauxite (Al2O3·3H2O) and diaspore. For Al2O3 with high purity requirements, it is generally prepared by chemical methods. Al2O3 has many isomorphous crystals, and there are more than 10 known types, and there are mainly three crystal forms, namely α-Al2O3, β-Al2O3, and γ-Al2O3. Among them, the structure is different and the properties are also different, and it is almost completely converted into α-Al2O3 at a high temperature above 1300 °C.

What is alumina catalyst support ?

Catalyst carrier, also known as support, is one of the components of supported catalysts. It is the skeleton of the active components of the catalyst, supports the active components, disperses the active components, and increases the strength of the catalyst. However, the carrier itself generally does not have catalytic activity.

Most carriers are products in the catalyst industry, commonly used alumina carriers.
