Lithium hydroxide is a small white monoclinic crystal. Lithium hydroxide has a spicy taste and strong alkalinity. Lithium hydroxide is placed in the air, it will absorb carbon dioxide and moisture. It is a chemical substance soluble in water. Lithium hydroxide is slightly soluble in ethanol and insoluble in ether. It is a corrosive substance.

The characteristics of lithium hydroxide

Lithium hydroxide is an inorganic substance with the chemical formula LiOH and the English name Lithium hydroxide. It is a small white monoclinic crystal with a spicy taste, strong alkalinity and corrosiveness. The pH of a 1mol/L solution is about 14, pKb = -0.04. It can absorb carbon dioxide and moisture in the air, soluble in water, slightly soluble in ethanol, and insoluble in ether. The relative density is 1.45, the melting point is 471°C (anhydrous), and it decomposes at 925°C. Available in anhydrous and monohydrate forms

Use of lithium hydroxide

Lithium hydroxide is an important basic lithium salt product. Lithium-based grease prepared from lithium hydroxide has the advantages of long service life, oxidation resistance, and high temperature stability; lithium hydroxide can be used as a developing agent for spectral analysis, Lubricant, as an additive for alkaline storage batteries, lithium hydroxide can increase the storage capacity and prolong the service life of the battery.

In addition, lithium hydroxide has important applications in metallurgy, atomic energy, chemical reagents, aerospace, defense industry and other fields. It can be used as an absorbent for carbon dioxide and can purify the air in the submarine.

Used to make lithium salt and lithium-based grease, electrolyte for alkaline storage batteries, lithium bromide refrigerator absorbing liquid, lithium soap (lithium soap), lithium salt, developer, etc. or as analytical reagents; petroleum, chemical, light industry, Used in the nuclear industry. When used in alkaline storage batteries, the aluminum content is not more than 0.06%, and the lead content is not more than 0.01%. Used as an analytical reagent, photographic developer, and also used in the manufacture of lithium; it is to be used as a raw material for the preparation of lithium compounds. It can also be used in metallurgy, petroleum, glass, ceramics and other industries.
