Lithium Hydroxide - Lithium Suisanka

LiOH (23.95). The monohydrate is obtained from aqueous solution by reaction of lithium carbonate with calcium hydroxide. The anhydrous form is obtained by dehydration with diphosphorus pentoxide in a vacuum. The anhydrous form is a white solid. Density 1.46 g cm ^-3 . Melting point 450 °C. Decomposes at 924 °C to Li ₂ O. Absorbs carbon dioxide. It is hygroscopic, soluble in water, slightly soluble in ethanol. Its aqueous solution is strongly alkaline. The monohydrate is a colorless monoclinic crystal. Density 1.51 g cm ^-3 . Soluble in water, insoluble in ether. Used in the manufacture of lithium compounds, photographic developers, batteries, carbon dioxide absorbents, greases, ceramics, etc. [CAS 1310-65-2: LiOH][CAS 1310-66-3: LiOH･H ₂ O]
