Product Description

Product Description

Silicon dioxide, with the formula SiO₂, is extremely common. It exists in multiple forms like quartz (crystalline) and amorphous types. Usually colorless and transparent in its pure state, it's a solid. Boasting a high melting point, it's insoluble in water and most solvents. Its structure, a network of silicon-oxygen covalent bonds, contributes to its stability and various physical traits.

Application

 

1. Glassmaking
Industrial-grade silica is pivotal for glass production. It forms the main structure, endowing glass with transparency, strength, and heat-resistance, suitable for everything from windows to glass containers.
2. Semiconductor Production
High-purity silica is essential in semiconductor manufacturing. It is used to make silicon wafers, the basis for integrated circuits, enabling the creation of advanced electronic devices.
3. Construction Materials
In construction, silica in the form of sand is a core ingredient in concrete and mortar. It significantly improves the strength and durability of buildings and infrastructure.
4. Refractory Applications
Silica is used to manufacture refractory materials for furnaces and kilns. These materials can endure high temperatures, ensuring smooth operation in industrial processes. 
5. Filler in Polymers
As a filler in plastics and rubbers, it enhances mechanical properties. It boosts strength, stiffness, and wear resistance, making products more robust.
