Aluminum Hydroxide Trihydrate used in many
industry applications
Aluminum hydroxide trihydrate, also known as hydrated alumina, is a chemical compound with various industrial applications. Here are some of its uses:
- Flame Retardant: Aluminum hydroxide trihydrate is widely used as a flame retardant in plastics, rubber, textiles, and other materials. It releases water vapor and acts as a heat sink, reducing the flammability and slowing down the spread of fire.
- Filler and Extender: It serves as a filler and extender in various industries, including plastics, ceramics, paints, and adhesives, to improve the mechanical properties, viscosity, and rheological behavior of the final products.
- Antacid: Aluminum hydroxide trihydrate is commonly used as an antacid medication to neutralize excess stomach acid and provide relief from heartburn, indigestion, and related gastrointestinal discomfort.
- Pharmaceutical Excipient: It is utilized as an excipient in pharmaceutical formulations, particularly in oral suspensions, chewable tablets, and antacid formulations, to improve palatability, stability, and drug delivery.
- Water Treatment: Aluminum hydroxide trihydrate is used in water treatment processes as a flocculating agent and coagulant to remove impurities, suspended solids, and colorants from drinking water and wastewater.
- Catalyst Support: It can serve as a support material for catalysts in various chemical reactions, including polymerization, hydrogenation, and dehydration reactions, enhancing catalytic activity and selectivity.
- Abrasive: Aluminum hydroxide trihydrate is employed as an abrasive material in polishing compounds, toothpaste formulations, and abrasive cleaners due to its mild abrasive properties and white color.
