What are the differences between aluminum hydroxide and aluminum oxide?

Aluminum oxide is obtained by processing bauxite through a series of processes to obtain aluminum hydroxide, which is then calcined. Therefore, the quantity of raw materials for alumina and aluminum hydroxide is the same, so what is the difference between the two? Let's follow alumina manufacturer Yangzhou Zhongtianli to learn more.

The difference between aluminum oxide and aluminum hydroxide is mainly due to differences in physical and chemical properties:

Physical properties: Aluminum hydroxide is a white colloidal substance that is insoluble in water and has strong adsorption ability. It can adsorb suspended solids and various pigments in water; Aluminum oxide is a white insoluble solid with high melting and boiling points.

Chemical properties: The chemical properties of aluminum hydroxide are unstable and easy to decompose upon heating. Not soluble in weak acids and bases, but soluble in strong acids and bases. Aluminum oxide is a typical oxide that does not react with water, but can react with acids and bases.

The different physical and chemical properties of the two also lead to differences in their uses. Aluminum oxide is often used as refractory material and is referred to as bauxite in mining, ceramics, and materials science. Aluminum hydroxide is used in various fuel industries and pharmaceutical industries.

There are many differences between aluminum hydroxide and aluminum oxide, and when choosing products, one needs to choose according to their own industry needs.
