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.
Sodium fluorosilicate has various functions in metal surface treatment:
3.1 Remove oxide layer and dirt
Sodium fluorosilicate can effectively remove oxide layers and dirt on metal surfaces during surface treatment. During metal processing and storage, metal surfaces are prone to forming oxide layers or being contaminated with various dirt, which can affect the quality of the metal surface. Sodium fluorosilicate, as a metal surface treatment agent, can effectively remove these oxide layers and dirt, thereby ensuring the cleanliness and smoothness of the metal surface.
3.2 Improve durability and wear resistance
Sodium fluorosilicate can enhance the durability and wear resistance of metal surfaces. In the field of metal surface treatment, the application of sodium fluorosilicate can significantly improve the durability and wear resistance of metal surfaces, and extend the service life of metals.
3.3 As an etchant and surface conditioner
Sodium fluorosilicate can also be used as an etchant and surface conditioner to further improve the quality of metal surfaces. Through etching treatment, small irregularities on the metal surface can be removed, making it smoother and improving the corrosion resistance and overall quality of the metal.
