Purity 99% White Crystal Powder Sodium Fluorosilicate, CAS 16893-85-9 Na2SiF6 SSF for Water Treatment
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 application of sodium fluorosilicate in water treatment mainly includes the following aspects:
3.1. Purification of water quality
Removing pollutants: Sodium fluorosilicate can react with heavy metal ions (such as lead, cadmium, etc.) and impurities such as silicates in water to form insoluble precipitates, effectively removing these pollutants. This ability has enabled sodium fluorosilicate to be widely used in wastewater treatment, drinking water purification, and industrial water treatment.
Stable pH value: By adjusting the pH value of the water body, sodium
fluorosilicate helps maintain the acid-base balance of the water
quality, ensuring that the water quality is within a safe range.
3.2. Prevent scaling and corrosion
Preventing scaling: Scaling is a common problem in water treatment systems, which can affect the normal operation of equipment and reduce treatment efficiency. Sodium fluorosilicate can combine with calcium and magnesium ions in water to form compounds that are not easily deposited, effectively preventing scaling from occurring.
Corrosion prevention: Sodium fluorosilicate can also prevent corrosion of metal
pipelines and equipment to a certain extent. By forming a
protective film or changing the electrochemical properties of
water, sodium fluorosilicate can reduce direct contact between
metals and water, thereby extending the service life of equipment.
3.3. Improve water treatment efficiency
The addition of sodium fluorosilicate can improve certain reaction
conditions in the water treatment process, such as enhancing
coagulation efficiency and accelerating precipitation rate, thereby
improving the overall water treatment efficiency. This makes the
water treatment process more efficient, energy-saving, and helps
reduce operating costs.
