What is Al4Si3O10(OH)2? Important knowledge about Al4Si3O10(OH)2.

  1. Definition of Al4Si3O10(OH)2
    Al4Si3O10(OH)2 is the chemical formula for a type of natural mineral known as kaolinite. The English name for this substance is also Kaolinite. Essentially, Al4Si3O10(OH)2 is a complex consisting of aluminum, silicon, oxygen, and hydrogen atoms. Each kaolinite molecule consists of four aluminum atoms, three silicon atoms, ten oxygen atoms, and two hydrogen atoms. The ionic structure of Al4Si3O10(OH)2 consists of aluminum ions Al3+, silicon ions Si4+, oxygen ions O2-, and hydroxide ions OH-.

  2. Properties of Al4Si3O10(OH)2
    Al4Si3O10(OH)2 (kaolinite) is solid at room temperature, with a white or light gray color, and has no distinctive smell. Kaolinite is a weak base, so it has a neutral pH level. The chemical properties of kaolinite show that it is insoluble in water, weak acids and bases, but soluble in strong acids.

  3. Typical chemical equations of Al4Si3O10(OH)2
    Kaolinite does not participate in normal chemical reactions with metals, acids, non-metals, or salts. However, when heated at high temperatures, it can decompose to produce other substances.

  4. Synthesis of Al4Si3O10(OH)2
    In nature, kaolinite is formed from the weathering of feldspar. In the lab, it can be synthesized through the reaction between silicon dioxide and aluminum hydroxide in a water environment. However, since this process is slow and requires strict conditions, it is not commonly used. In industry, kaolinite is directly mined from natural kaolin clay deposits.
