Dehydration of organic solvents: Because alumina has good water absorption, it can effectively remove the water in organic solvents, ensuring the purity and stability of the solvent.
Adsorbent: Alumina is widely used as an adsorbent because of its ability to adsorb a variety of substances, including water, gases, and other impurities.
Organic reaction catalyst: In the chemical industry, alumina is often used as a catalyst to promote the progress of organic reactions and improve the reaction rate and yield.
Abrasives and polishes: Due to the high hardness of alumina, it is often used as an abrasive and polishes for the grinding and polishing of metals, glass and other materials.
Raw materials for smelting aluminum: Aluminum oxide is the main raw material for the production of metal aluminum, and pure aluminum can be obtained through electrolytic aluminum oxide.
Refractory: The high melting point of alumina makes it an excellent refractory material for the manufacture of refractory bricks, crucibles and other high temperature equipment.
The main component of rubies and sapphires: Alumina is the main component of rubies and sapphires, and these two gemstones show different colors because they contain different impurities.
Fluoride removal agent for high fluoride drinking water: aluminum oxide can effectively remove fluoride ions in drinking water and prevent fluorine poisoning.
Gas drying: In the oxygen industry, textile industry, electronics industry, etc., alumina is used as a gas desiccant to remove water in the gas.
Additives for friction materials: aluminum oxide can improve the hardness, wear resistance and high temperature stability of friction materials, and is used to manufacture brake pads, clutch pads and so on.
Raw materials for ceramics and glass: Alumina is also widely used in the manufacture of ceramics and glass, which can improve the hardness, transparency and gloss of products.
