What is a Aluminum Silicate (Al₂SiO₅ or Al₂O₃·SiO₂)?

Aluminum silicate is a compound composed of aluminum, silicon, and oxygen. It occurs naturally as minerals such as kaolinite, andalusite, and sillimanite, and is commonly found in clay, soil, ceramics, and refractory materials.

Due to its excellent heat resistance and insulating properties, aluminum silicate is used in the production of ceramics, refractory bricks, construction materials, and as an additive in cosmetics and pharmaceuticals. In cosmetics, it enhances smoothness and absorbency, while in medicine, it can act as an antacid to neutralize stomach acid.
