설명

일반 설명

Lithium tetraborate (Li₂B₄O₇) is a piezoelectric material. It can be synthesized from boric acid. Its pyroelectric, piezoelectric and dielectric properties have been evaluated. 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.

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

애플리케이션

Used as a spectroscopic fluxing agent.
