Product Description

Product Description

Silicon dioxide, with the chemical formula SiO₂, is one of the most abundant compounds on Earth. It exists in different crystalline forms like quartz, as well as amorphous forms. Typically, it appears as a colorless, transparent solid in its purest form, but can also be found as white powders. It has a high melting point, is insoluble in water and most common solvents, and is chemically stable under normal conditions.

Application

 

1. Glass Manufacturing
In glass production, silica is the primary component. It imparts transparency, hardness, and heat-resistance to glass products, from everyday window panes to laboratory glassware.
2. Semiconductor Industry
High-purity silica is crucial in the semiconductor industry. It is used to make silicon wafers, which are the foundation for integrated circuits, enabling the miniaturization of electronic devices.
3. Construction
In construction, silica-based materials like sand are used in mortar and concrete. They enhance the strength and durability of these building materials.
4. Cosmetics
Silica is added to cosmetics. It acts as an absorbent, controlling oiliness, and as a thickening agent, improving the texture of products such as powders and creams.
5. Food Industry
As an anti-caking agent, silica prevents clumping in powdered foods like spices and milk powder, ensuring free-flowing properties.
