Chemical compound

Lithium borate,[1] also known aslithium tetraborate,[2]dilithium tetraborate[3] orboron lithium oxide[2] is aninorganic compound with the formula Li2B4O7. A colorless solid, lithium borate is used in makingglasses andceramics. It is not to be confused with B8Li2O13, also called lithium borate.[4]

Structure

[edit]

Its structure consists of a polymeric borate backbone. The Li+ centers are bound to four and five oxygen ligands. Boron centers are trigonal and tetrahedral.[5][6]

Borate backbone of Li2B4O7.

Lithium borate can be used in the laboratory asLB buffer forgel electrophoresis ofDNA andRNA. It is also used in the borax fusion method tovitrify mineral powder specimens for analysis byWDXRF spectroscopy.[7]
