The nature and use
of inorganic salts in the field of raw materials for chemical production
Abstract

This paper introduces in detail the nature and use of inorganic salts in the field of raw materials for chemical production. Through the discussion of the physical and chemical properties of inorganic salts, its important position in chemical production is expounded. At the same time, according to the different types of inorganic salts, listed its wide range of applications, including food, medicine, metallurgy, ceramics and so on. The purpose of this paper is to provide a comprehensive overview of the nature and use of inorganic salts in the field of chemical production.

1. Introduction

Inorganic salts are widely used in the field of chemical production raw materials. They have unique physical and chemical properties and play a key role in the smooth progress of the chemical production process. Understanding the nature and use of inorganic salts is of great significance for improving chemical production efficiency, reducing costs and expanding application fields.

2. the nature of inorganic salt

1. physical properties: inorganic salt usually has a higher melting point, boiling point and density, with good thermal stability and chemical stability. In addition, many inorganic salts are hygroscopic and easily absorb moisture in the air.
2. Chemical properties: Inorganic salts usually have a high degree of dissociation in solution and can dissociate the corresponding cations and anions. In addition, inorganic salts can also undergo chemical reactions such as metathesis and redox.

3. the use of inorganic salts

1. food industry: many inorganic salts in the food industry as food additives, such as sodium chloride (salt), pyrite (sulfate), phosphate and so on. They can improve the taste, color and preservation of food, and supplement the trace elements needed by the human body.
2. Pharmaceutical industry: Inorganic salts are widely used as pharmaceutical raw materials and excipients in the pharmaceutical industry. For example, calcium carbonate is used as a calcium supplement, magnesium sulfate is used as a laxative, potassium chloride is used to regulate fluid balance, etc.
3. Metallurgical industry: In the metallurgical industry, inorganic salts are used as flux, desulfurizer and deoxidizer in the smelting process. For example, fluorite (calcium fluoride) is used as a flux in the steelmaking process, which can reduce the melting point and improve smelting efficiency.
4. Ceramic industry: inorganic salts are used as raw materials in the ceramic industry, such as silicate, alumina, etc. They form a hard ceramic material by high temperature sintering, which has excellent heat resistance, corrosion resistance and insulation.
5. Environmental protection: Inorganic salts also play an important role in the field of environmental protection, such as wastewater treatment and soil remediation. For example, inorganic coagulants such as iron salts and aluminum salts can remove suspended solids and colloidal substances during wastewater treatment.

4. conclusion

inorganic salt has a wide range of applications in the field of chemical production raw materials, and its unique physical and chemical properties make it play an important role in many fields. Understanding and mastering the nature and use of inorganic salts will help to improve chemical production efficiency, reduce costs, expand application areas, and promote the sustainable development of the chemical industry.
