Properties of Aluminium Silicate
- Soft and Fine: Aluminium Silicate is a soft and fine powder that has a smooth texture.
- High Plasticity: It has high plasticity, which means it easily molds and shapes into any desired form.
- Low Abrasiveness: It has low abrasiveness, which makes it ideal for use in cosmetics and pharmaceuticals.
- High Opacity: Being a white pigment, it can help to cover the surface on which it is applied. This is important for getting a smooth, even finish as a component in wood primer.
- Water Resistant: As a water repellent material, it can help in prevention of damage from moisture.
- Low Cost: Aluminium silicate is a relatively inexpensive filler, so it can help to reduce the cost of the final product.
Applications
- Paints: Aluminium Silicate is the base mineral filler in wood varnishes and paints. Wood primers containing this mineral provide a smoother finish as well as a protective layer to the wood
- Ceramics: It is a key ingredient in the production of ceramics such as porcelain and fine china. It functions as a binder and filler in the clay mixture. Herein, it helps to improve the strength and whiteness of the finished product.
- Paper: As a coating agent in paper production it helps to improve the surface quality and printability of the paper.
- Cosmetics: As a natural absorbent and a thickening agent, it is an important ingredient in face masks, scrubs, and powders. It also has a neutral pH level that make it more versatile.
- Pharmaceuticals: As an excipient in pharmaceuticals, it helps to improve the flowability and compressibility of tablets and capsules.
