Lithium borate,[1] also known as lithium tetraborate,[2] dilithium tetraborate[3] or boron lithium oxide[2] is an inorganic compound with the formula Li2B4O7. A colorless solid, lithium borate is used in making glasses and ceramics. It is not to be confused with B8Li2O13, also called lithium borate.[4]
Structure
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]
Lithium borate can be used in the laboratory as LB buffer for gel electrophoresis of DNA and RNA. It is also used in the borax fusion method to vitrify mineral powder specimens for analysis by WDXRF spectroscopy.[7]
