Lithium borate, also known as lithium tetraborate (Li2B4O7), is the lithium salt of boric acid. Lithium borate is an ingredient for use in making glasses and ceramics.

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.[1]
