Lithium hydroxide is a white monoclinic fine crystal. Lithium hydroxide has a spicy taste and is strongly alkaline. When lithium hydroxide is placed in the air, it absorbs carbon dioxide and moisture. It is a water-soluble chemical substance. Lithium hydroxide is slightly soluble in ethanol and insoluble in ether. It is a corrosive substance.
Properties of Lithium Hydroxide
Lithium hydroxide is an inorganic substance, the chemical formula is LiOH, the English name is Lithium hydroxide, it is a white monoclinic fine crystal, has a spicy taste, is strongly alkaline, corrosive, the pH of a 1mol/L solution is about 14, pKb = -0.04. Can absorb carbon dioxide and water in the air, soluble in water, slightly soluble in ethanol, insoluble in ether. The relative density is 1.45, the melting point is 471 °C (anhydrous), and decomposition occurs at 925 °C. Available in both anhydrous and monohydrate forms
Uses of Lithium Hydroxide
Lithium hydroxide is an important basic lithium salt product. Lithium-based grease prepared with lithium hydroxide has the advantages of long service life, oxidation resistance, high temperature stability, etc. Lithium hydroxide can be used as a developing agent for spectral analysis, Lubricating oil, as an additive for alkaline batteries, lithium hydroxide can increase storage capacity and prolong battery life.
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 submarines.
It is used to make lithium salt and lithium-based grease, electrolyte of alkaline battery, absorption liquid of lithium bromide refrigerator, lithium soap (lithium soap), lithium salt, developer, etc. or as analytical reagents; petroleum, chemical, light industry, nuclear industry, etc. When used in alkaline batteries, the aluminum content is not more than 0.06%, and the lead content is not more than 0.01%. It is used as an analytical reagent, a photographic developer, and also in the manufacture of lithium; it is used as a raw material for the preparation of lithium compounds. It can also be used in metallurgy, petroleum, glass, ceramics and other industries.
