The nature and use
of potassium fluoride in the field of chemical production raw materials
1. Introduction

potassium fluoride is an important inorganic salt, widely used in chemical industry, metallurgy, medicine and other fields. As a raw material for chemical production, potassium fluoride has unique properties and uses. This article will detail the properties of potassium fluoride and its application in the field of chemical production raw materials.

2. properties of potassium fluoride

1. physical properties: potassium fluoride is colorless cubic crystal or white powder, melting point of 858 ℃, boiling point of 1497 ℃, density of 2.454 g/cm ³. Potassium fluoride is easily soluble in water, and the solubility increases with increasing temperature.
2. Chemical properties: Potassium fluoride has strong reactivity and can react with many acids, bases and salts. The aqueous solution of potassium fluoride is alkaline and can react with acid to form the corresponding potassium salt and fluoride. In addition, potassium fluoride is also reductive and can be oxidized by strong oxidants.

3. the use of potassium fluoride

1. chemical production: potassium fluoride in chemical production as raw materials, can be used for the preparation of hydrogen fluoride, potassium hydroxide and other chemicals. In addition, potassium fluoride can also be used in the manufacture of fluorite glass, optical glass and other special glass.
2. Metallurgical industry: In the metallurgical industry, potassium fluoride can be used as a flux to extract metal elements. For example, in the aluminum smelting process, potassium fluoride can be used as an electrolyte to improve the purity of aluminum.
3. Pharmaceutical industry: Potassium fluoride can be used as raw materials or excipients for the treatment of certain diseases in the pharmaceutical industry. For example, potassium fluoride can be used in the preparation of antacids for the treatment of gastric hyperacidity.
4. Other fields: In addition to the above fields, potassium fluoride can also be used in the manufacture of ceramics, soap, printing and dyeing industries.

4. conclusion

potassium fluoride as an important inorganic salt, has a wide range of applications in the field of chemical production raw materials. Its unique properties and functions make potassium fluoride play an important role in many fields. With the continuous development of science and technology, the application field of potassium fluoride will be further expanded and bring more contributions to human society.
