使用Lithium metaborate is used for flux.
一般的な説明Lithium metaborate (LiBO2) is the lithium salt of boric acid. It can be synthesized by reacting orthoboric acid with lithium carbonate. Its crystals belong to the monoclinic crystal system having space group P21/c. Three polymorphic forms have been identified on ambient pressure devitrification of LiBO2: α-, γ- and β′-LiBO2.
製造方法Lithium metaborate, LiBO2, may be prepared by fusing together either lithium hydroxide or lithium carbonate and boric acid in the proper stoichiometric ratio. Recrystallization from water at about room temperature yields lithium metaborate- octahydrate, LiBO2·8H2O. The octahydrate may be dried to yield a dihydrate, LiBO2-2H2O, or a half-hydrate, LiBO2·0.5H2O.
