1. Sodium Fluorosilicate Introduction
Sodium fluorosilicate, also known as sodium silicofluoride, is a chemical compound with the formula Na2SiF6. This odorless, white crystalline powder is commonly used in various industrial applications such as water fluoridation, metal surface treatment, and glass etching. It is a source of fluoride ions and is valued for its ability to resist acidic conditions. Sodium fluorosilicate plays a crucial role in enhancing the durability and strength of materials where it is applied.

3. Sodium Fluorosilicate Applications
The main application areas of sodium fluorosilicate include wood preservation, concrete admixtures, ceramic glazes, and glass manufacturing. In wood preservation, sodium fluorosilicate can react with the moisture in the wood to generate fluoride with anti-corrosion properties, thereby protecting the wood from pests and mold. In concrete admixtures, it can improve the fire resistance and water resistance of concrete. In addition, sodium fluorosilicate is also used in the preparation of ceramic glazes, which can improve the smoothness and hardness of the glaze surface. In glass manufacturing, it helps to improve the transparency and strength of the glass.
The role of sodium fluorosilicate in high borosilicate glass
1. Improve borosilicate glass corrosion resistance
Sodium fluorosilicate can generate sodium fluorosilicate in glass, which is an inorganic non-metallic material with excellent properties such as high temperature resistance, acid resistance, and strong alkali resistance. The sodium fluorosilicate film formed on the surface of glass can effectively prevent the glass from being damaged by chemical corrosion such as acid and alkali, and is widely used in industries, metallurgy, and other fields.
2. Improve borosilicate glass mechanical strength
Sodium fluorosilicate can also improve the mechanical strength of glass. During the glass processing, sodium fluorosilicate can be fully mixed with other materials, making the glass have higher toughness and hardness, and helping to improve the heat resistance and wear resistance of the glass.
3. Improve borosilicate glass transparency
Sodium fluorosilicate can reduce the refractive index of glass and improve its transparency. It can form colorless and transparent silicon fluoride in glass, thereby reducing the reflectivity of the glass surface and increasing its transmittance.
