White powder용도
Lithium metaborate is used for flux.제조 방법
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.일반 설명
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.Structure and conformation
Lithium metaborate has several crystal forms.Below 100 °C, LiBO2·8H2O is firstly dehydrated to a lower hydrate LiBO2·2H2O [1].
When the temperature is higher than 190°C, the dehydrated amorphous hydrate could crystallize into other poorly crystalline phases designated as LiBO2·xH2O (x=0.3/0.5)[2].
An anhydrous monoclinic α-LiBO2 could be obtained when the baking temperature reaches 600 °C. The α form consists of infinite chains of trigonal planar metaborate anions [BO2O-]n.
At 950 °C, by applying 15 kbar of pressure to a LiCl flux containing α-LiBO2, α-LiBO2 could be converted to metastable γ-LiBO2 crystals which were small, but of high quality[3]. γ-LiBO2 has tetragonal symmetry with lattice parameter a=4.1961 ?, c=6.5112 ?, space group I-42d and a density of 2.882 g/cm3.
