Read： 564 Time：20months ago Source：Transform the World with Simplicity

Lithium chloride is an important inorganic salt, which is widely used in the field of chemical production raw materials. This article will detail the properties and uses of lithium chloride.

1. the nature of lithium chloride

lithium chloride is a white crystalline powder with strong hygroscopicity. It is easily soluble in water, and its solubility increases with increasing temperature. Lithium chloride is highly corrosive and can destroy the oxide film on the surface of the metal, which is corrosive to the metal. In addition, lithium chloride has high thermal stability and can exist stably at high temperatures.

2. the use of lithium chloride

1. preparation of lithium metal

lithium chloride is one of the important raw materials for the preparation of lithium metal. By electrolyzing the lithium chloride molten salt, metallic lithium having a relatively high purity can be obtained. Lithium metal is widely used in batteries, alloys, ceramics and other fields.

2. Desiccant

Lithium chloride has strong hygroscopicity and can be used as a desiccant. In some occasions that require strict control of humidity, such as precision machinery, electronic equipment and other fields, lithium chloride can be used as a desiccant to protect the equipment from moisture erosion.

3. ceramic industry

lithium chloride can be used as a flux in the ceramic industry, which can reduce the sintering temperature of ceramics and improve the density and mechanical properties of ceramics.

4. pharmaceutical industry

lithium chloride in the pharmaceutical industry can be used as a drug for the treatment of mania. It can regulate the balance of neurotransmitters in the human body and relieve manic symptoms.

5. Other fields

In addition to the above fields, lithium chloride can also be used to prepare other chemicals, such as zinc chloride, ferric chloride, etc. In addition, lithium chloride can also be used in the preparation of catalysts and lubricants in the petroleum industry.

In conclusion, as an important inorganic salt, lithium chloride is widely used in the field of chemical production raw materials. Understanding the properties and uses of lithium chloride is of great significance for the rational use of resources and the development of new applications.
