Introduction:

Lithium hydroxide is one of the most important lithium compounds, there are two kinds of anhydrous LiOH and LiOH·H2O. Anhydrous LiOH is white tetragonal crystal particles or fluid powder, with a relative density of 1.45g/cm3, a melting point of 471.2°C and a boiling point of 1620°C. Lithium hydroxide monohydrate is a white deliquescent single crystal powder with a phase density of 1.51g/cm3 and a melting point of 680°C. When the temperature is higher than 100°C, it loses crystal water and becomes anhydrous LiOH. LiOH is soluble in water, slightly soluble in alcohol, and easily absorbs CO2 in the air to form Li2CO3. LiOH and its concentrated solution are corrosive, and can corrode glass and ceramics at normal temperatures.

 

Application:

LiOH is one of the main raw materials for the production of advanced lithium-based grease. Lithium hydroxide is widely used in chemical raw materials, chemical reagents, battery industry, petroleum, metallurgy, glass, ceramics and other industries. It is also used in national defense industry, atomic energy industry and An important raw material for the aerospace industry. Lithium-based grease produced by lithium hydroxide has long service life, strong water resistance, good fire resistance, difficult to oxidize, stable performance during multiple heating-cooling-heating cycles, and the applicable temperature range can be from -50°C to +300°C. Widely used in the lubrication of military equipment, aircraft, automobiles, rolling mills and various mechanical transmission parts. In the battery industry, lithium hydroxide is used as an additive for alkaline storage batteries and nickel-metal hydride batteries, which can prolong battery life and increase storage capacity.
