Lithium borate,[https://www.chemspider.com/Chemical-Structure.21169645.html Lithium borate] also known as lithium tetraborate,[https://commonchemistry.cas.org/detail?cas_rn=12007-60 Boron lithium oxide] dilithium tetraborate[https://webbook.nist.gov/cgi/cbook.cgi?ID=C12007602 dilithium tetraborate] or boron lithium oxide 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.[https://webbook.nist.gov/cgi/cbook.cgi?ID=C12008401 Lithium borate]
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.{{cite journal|journal=Journal of Alloys and Compounds|volume=428|year=2007|pages=290–296|title=Li2B4O7 Crystal structure in anharmonic approximation at 20, 200, 400 and 500 °C|author1=Sennova, N. |author2=Bubnova, R. |author3=Shepelev, Yu. |author4=Filatov, S. |author5=Yakovleva, O. |issue=1–2|doi=10.1016/j.jallcom.2006.03.049}}{{cite journal|title=Temperature-dependent Changes of the Crystal Structure of Li2B4O7|author=Natalia Sennova.

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.Ron Jenkins, X-Ray Fluorescence Spectrometry, Second Edition, J. Wiley & Sons Inc., 1999, {{ISBN|0-471-29942-1}}, p 146-7.
