Aluminum compounds are a class of chemical substances whose main components are compounds of aluminum and other non-metallic elements. Aluminum compounds are widely used in industry for the production and processing of materials. Among them, aluminum oxide is one of the most common aluminum compounds. It has the characteristics of high melting point, high temperature resistance, and corrosion resistance, so it is used as a raw material for materials such as ceramics, glass, and cement. In addition, aluminum phosphate is a common inorganic gelling agent, which is often used in the curing process of materials such as cement and ceramics. Aluminum compounds are also used as raw materials for abrasive materials such as abrasives and sandpaper. These materials have important applications in metal processing, glass processing and other fields.
