Applicazioni

Used in borate fusion sample preparation of various samples for analysis by XRF, AAS, ICP-MS, ICP-AES and ICP-OES. Used to determine the trace level of elements in contaminated soil. Useful fod dissolving acidic oxides such as SiO<sub>2</sub>, and Fe<sub>2</sub>O<sub>3</sub>. A mixture of lithium metaborate and lithium tetraborate is useful for dissolving most of the inorganic oxides to enable spectrochemical analysis.

Note

Stable compound. Reactive towards strong reducing agents such as metal hydrides, acetic anhydride or alkali metals.
