Introduction to Aluminum Hydroxide Powder
2023-12-12


Aluminum hydroxide powder is a crucial inorganic compound powder. Aluminum hydroxide powder, with the chemical formula Al(OH)₃, is also referred to as aluminum hydroxide or monohydrate aluminum oxide (HAlO₂·H₂O). It appears as a white or light - colored powder, odorless, insoluble in water, yet soluble in hot sulfuric acid, hydrochloric acid, and alkalis. Aluminum hydroxide powder exhibits amphoteric properties. It can react with acids to form salts and water, and with strong bases to yield salts and water as well. In the industrial realm, aluminum hydroxide powder serves as an intermediate product in the extraction of alumina from bauxite. It is primarily utilized in aluminum smelting and can also function as a flame - retardant filler, finding extensive application in industries such as plastics, rubber, coatings, and building materials. As a flame retardant, aluminum hydroxide powder not only provides flame - retardant effects but also inhibits smoking, prevents droplet formation, and does not generate toxic gases, thus being widely adopted. Moreover, aluminum hydroxide powder has medical applications. It is commonly employed to treat excessive stomach acid. The main component of stomach acid is hydrochloric acid, and aluminum hydroxide powder can react with it to produce non - toxic and harmless aluminum chloride, which is then excreted from the body, thereby alleviating the symptoms of hyperacidity. It should be noted that aluminum hydroxide powder poses certain risks to the human body. Direct contact may irritate the eyes and skin mucous membranes. Additionally, when exposed to aluminum products, there is a potential for inhaling aluminum dust, which can harm the lungs and lead to alveolar epithelial hyperplasia. Therefore, appropriate protective measures must be taken when handling aluminum hydroxide powder.
