the properties and uses of fluosilicic acid solution
Abstract:

This paper introduces the properties and uses of fluosilicic acid solution in detail, including its physical properties, chemical properties, production process, main uses and safety precautions. Fluorosilicic acid solution has important application value in the field of chemical production raw materials, which can be used to prepare fluoride, silicate and other compounds, as well as as electrolyte, catalyst and so on.

1. the nature of fluosilicic acid solution

1. physical properties

fluosilicic acid solution is a colorless and transparent liquid with a pungent odor. Its density increases with the increase of concentration, the viscosity is low, and it has good fluidity. Fluorosilicic acid solution has a high boiling point and is not volatile.

2. chemical properties

fluorosilicic acid solution has strong acidity, can react with metal, metal oxide, alkali and other substances. Fluorosilicic acid solution is also reductive and can be oxidized by strong oxidants. In addition, the fluorosilicic acid solution also has good thermal stability and can be used at high temperatures.

2. The use of fluorosilicic acid solution

1. Preparation of fluoride

Fluorosilicic acid solution can be used to prepare various fluorides, such as sodium fluoride, potassium fluoride, calcium fluoride, etc. These fluorides are widely used in metallurgy, chemical industry, glass, ceramics and other fields.

2. Preparation of Silicate

A fluorosilicic acid solution can be reacted with an alkali metal hydroxide to form the corresponding silicate. Silicate has a wide range of applications in the construction, ceramics, glass and other industries.

3. as an electrolyte

fluorosilicic acid solution can be used as an electrolyte for electrolytic preparation of hydrofluoric acid, metal fluoride, etc. In addition, the fluorosilicic acid solution can also be used in electroplating, electropolishing and other processes.

4. as a catalyst

fluorosilicic acid solution can be used as a catalyst to promote certain chemical reactions. For example, in an esterification reaction, a fluorosilicic acid solution can promote the formation of an ester from a carboxylic acid and an alcohol.

3. the production process of fluosilicic acid solution

The production process of fluosilicic acid solution mainly includes acidolysis and electrolysis. The acid hydrolysis method is to react silica with hydrofluoric acid to generate fluorosilicic acid and silicon tetrafluoride gas, and then cool and absorb the gas to obtain fluorosilicic acid solution. The electrolysis method is to obtain sodium hydroxide and chlorine by electrolyzing salt water, and then react sodium hydroxide with fluorosilicic acid to obtain sodium fluorosilicate, and finally obtain fluorosilicic acid solution by acid hydrolysis of sodium fluorosilicate.
Precautions for safe use of
4.

When using fluosilicic acid solution, you need to pay attention to the following matters: avoid contact with skin, eyes and respiratory tract; store in a cool and ventilated place, away from fire and heat sources; avoid contact with alkaline substances; Wear personal protective equipment such as protective gloves and goggles when using.

5. conclusion

fluosilicic acid solution has a wide range of application value in the field of chemical production raw materials, can be used for the preparation of fluoride, silicate and other compounds, as well as as electrolyte, catalyst and so on. Pay attention to safety during use and avoid contact with sensitive parts such as skin and eyes.
