Reference Information
| Introduction | lithium hydroxide is one of the most important lithium compounds, there are two kinds of anhydrous LiOH and LiOH · H2O. Anhydrous LiOH is a white tetragonal crystal particle or flowable powder with a relative density of 1.45g/cm3, a melting point of 471.2 ℃ and a boiling point of 1620 ℃. Lithium hydroxide monohydrate is a White deliquescent single crystal powder with a relative density of 1.51g/cm3 and a melting point of 680 ° C. When the temperature is higher than 100 ° C., the loss of crystal water becomes anhydrous LiOH. LiOH soluble in water, slightly soluble in alcohol, easy to absorb CO2 in the air to generate 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 grease, lithium hydroxide is widely used, mainly used in chemical raw materials, chemical reagents, battery industry, petroleum, metallurgy, glass, ceramics and other industries, but also the defense industry, atomic energy industry and aerospace industry is an important raw material. Lithium grease produced by lithium hydroxide has long service life, strong water resistance, good fire resistance, difficult oxidation, and stable performance during multiple heating-cooling-heating cycles, the applicable temperature range can be from -50 ℃ to +300 ℃, which is widely used for lubrication of military equipment, aircraft, automobile, rolling mill and various mechanical transmission parts. In the battery industry, lithium hydroxide is used as an additive for alkaline storage batteries and nickel-hydrogen batteries, which can prolong the battery life and increase the power storage. |
| production method | lithium carbonate causticization method: the refined milk of lime is mixed with lithium carbonate. Mixing at a ratio of 08: 1, adjusting the concentration of the causticizing solution to 18g/ L to 20g/ L, heating to boiling and vigorous stirring, causticizing for about 30min. The reaction is as follows: the reaction can give a concentration of about 3. 5% LiOH solution. The insoluble residue was removed, separated, and the mother liquor was concentrated under reduced pressure and crystallized to obtain lithium hydroxide monohydrate. The lithium hydroxide monohydrate was dried at 130 ° C. To 140 ° C. And heated under reduced pressure at 150 ° C. To 180 ° C. To obtain anhydrous LiOH. The production of lithium hydroxide by causticization of lithium carbonate is currently the main method for the production of lithium hydroxide at home and abroad, especially abroad. |
| solubility in water (g/100ml) | grams dissolved per 100ml of water at different temperatures (℃): 12.7g/0 ℃;12.7g/10 ℃;12.8g/20 ℃;12.9g/30 ℃;13g/40 ℃;13.3g/50 ℃; 13.8g/60 ℃;15.3g/80 ℃;17.5g/100 ℃ |
| Application | is mainly used as a raw material for the preparation of lithium compounds. It can also be used in metallurgy, petroleum, glass, ceramic and other industries. for the preparation of lithium salt and lithium grease, alkaline battery electrolyte, lithium bromide refrigerator absorption liquid, etc. |
