Description

General description

Lithium tetraborate (Li₂B₄O₇) is a piezoelectric material.[1] It can be synthesized from boric acid.[2] Its pyroelectric, piezoelectric and dielectric properties have been evaluated.[3] It is a widely used material in the field of non-linear optics. Its electronic structure has been investigated by x-ray photoelectron spectroscopy (XPS) and quantum mechanical modelling methods.[4]

Lithium tetraborate is a pyroelectric and piezoelectric material with potential applications in pressure sensors and surface acoustic wave (SAW) devices.[5][6][7] In the presence of activators such as terbium and cupric ions, it shows thermoluminesence property.[8]

Application

Used as a spectroscopic fluxing agent.
