Silicon dioxide, with the chemical formula SiO ₂, is one of the most abundant compounds in the Earth's crust and one of the most common substances in our daily lives. From ancient glass manufacturing to modern high-tech industries, silicon dioxide is ubiquitous and plays an indispensable role.
The cornerstone of traditional industry:
Glass industry: Silicon dioxide is the main raw material for manufacturing glass, accounting for over 70% of the glass composition. Different types of glass, such as flat glass, vessel glass, optical glass, etc., require the use of silica with different purity and particle size.
Ceramic industry: Silicon dioxide is an important component of ceramic bodies and glazes, which can improve the strength, wear resistance, and heat resistance of ceramics.

Foundry industry: Silicon dioxide sand is a commonly used molding material in casting production, used to manufacture molds and cores.
Rubber industry: As a rubber filler, silica can improve the strength, wear resistance and anti-aging properties of rubber.
Stars in the high-tech field:
Electronic industry: High purity silicon dioxide is an important material for manufacturing semiconductor devices, integrated circuits, and optical fibers.
Photovoltaic industry: Silicon dioxide is the main raw material for manufacturing solar panels, and its purity directly affects the conversion efficiency of solar cells.
Cosmetics industry: Nano silica is widely used in sunscreen, foundation make-up and other cosmetics because of its excellent adsorption, dispersion and stability.
Pharmaceutical industry: Silicon dioxide can be used in fields such as drug carriers, medical dressings, and biosensors.
Future Development Trends:
High purity: With the rapid development of high-tech fields such as electronics and photovoltaics, the demand for high-purity silica will continue to grow.
Nanoization: Nano silica has broad application prospects in fields such as new energy and biomedicine due to its unique properties.
