Application of Aluminium Hydroxide

  1. Flame Retardant: Aluminium Hydroxide is widely used as a flame retardant in plastics and rubber. It decomposes at high temperatures to release water vapor, which cools the material and dilutes flammable gases, reducing the risk of fire.
  2. Antacid: In pharmaceuticals, it acts as an antacid to neutralize excess stomach acid, providing relief from heartburn and indigestion. Its effectiveness and safety make it a preferred choice in over-the-counter medications.
  3. Filler: Used as a filler in paper and paints, Aluminium Hydroxide enhances the opacity and brightness of products. It also improves the mechanical properties of materials, making them more durable.
  4. Water Treatment: It serves as a coagulant in water treatment processes, helping to remove impurities and improve water clarity. Its ability to form flocs makes it effective in sedimentation and filtration systems.
  5. Ceramics: In the ceramics industry, Aluminium Hydroxide is used to produce alumina, a key component in the manufacture of high-strength ceramics. Its purity and consistency are crucial for producing high-quality ceramic products.
