| Lithium tetraborate white crystal. Melting point 930 ℃. Slightly soluble in water, insoluble in ethanol and other organic solvents. Usually it is pentahydrate. Lithium pentaborate (Li2B10O16) is often octahydrate, a white powder with a relative density of 1.72, and loses all crystal water at 300-350 ℃. Both can be prepared by melting and reacting lithium hydroxide and boric acid together. Used as porcelain glaze. | |||||||||
