The basic properties
of 1. sodium fluorosilicate
sodium fluorosilicate is a white crystalline powder that is stable at room temperature. It can be mixed with water to produce fluosilicate ions and sodium ions. The molecular formula of sodium fluosilicate is Na2SiF6 · 6H2O, and the relative molecular mass is 264.08. It has a density of 2.68g/cm³, a melting point of 1000°C and a boiling point of 2200°C.

2. the use of sodium fluorosilicate

1. industrial use

of sodium fluorosilicate in industry has a wide range of applications, such as metal smelting, ceramic industry, fireproof materials production, Portland cement production. It can be used as a flux for casting and melting metal aluminum and copper, a production agent for alumina and a glass manufacturing additive. In the ceramic industry, sodium fluorosilicate can be used as glaze and porcelain material to improve its hardness and luster.

2. medical use

sodium fluosilicate is an important pharmaceutical raw material, can be used in the manufacture of aluminum fluosilicate sodium stomach powder, sodium fluosilicate lotion. It can also act as a stabilizer and buffer in biological preparations.

3. environmental protection use

sodium fluosilicate can be used as sewage treatment agent and pollution prevention agent. It can accelerate the precipitation of suspended solids and purify sewage; and it has the function of preventing rust and can be used to protect the surface of steel.

4. Other uses

sodium fluosilicate has other uses, such as food additives and vegetable cleaners, and is also used in pesticides and herbicides in agricultural production.

3. Application
of Sodium Fluorosilicate
1. Aluminum fluoride produced by aluminum method is one of the key raw materials for the production of high purity aluminum. Sodium fluosilicate is an important raw material for the preparation of aluminum fluoride.

2. Sodium fluorosilicate can be used as glaze and porcelain material to improve its hardness and luster. It is widely used in ceramic production, involving all kinds of porcelain in daily life.

3. Sodium fluosilicate is the main raw material for the production of copper sulfate. Copper sulfate is an important raw material in industrial production and is widely used.
