|Section2= |Section4= |Section7= }} Lithium metaborate (LiBO2) is a chemical compound. ==Applications== Lithium metaborate or lithium tetraborate (Li2B4O7), or a mixture of both, can be used in borate fusion sample preparation of various samples for analysis by XRF, AAS, ICP-OES, ICP-AES and ICP-MS. Simultaneous determination of parts-per-million level Cr, As, Cd and Pb, and major elements in low level contaminated soils using borate fusion and energy dispersive X-ray fluorescence spectrometry with polarized excitation.〔()〕 Lithium metaborate dissolves acidic oxides such as SiO2 and Fe2O3, where the stoichiometric ratio of oxygen to cation, ''y/x'' in MxOy, is greater than unity. Lithium tetraborate dissolves basic oxides such as CaO, MgO and other oxides of the alkali metals and alkaline earth metals, where ''y/x'' ≤ 1. Most oxides are best dissolved in a mixture of the two lithium borate salts, for spectrochemical analysis.〔Fernand Claisse, "Fusion and fluxes," ''Comprehensive Analytical Chemistry: Sample Preparation for Trace Element Analysis'', Vol. 41, Elsevier, 2003, p 301-311.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lithium metaborate」の詳細全文を読む スポンサード リンク
