Lithium niobate (LiNbO3) is a synthetic salt consisting of niobium, lithium, and oxygen. Its single crystals are an important material for optical waveguides, mobile phones, piezoelectric sensors, optical modulators and various other linear and non-linear optical applications.[6] Lithium niobate is sometimes referred to by the brand name linobate.[7]
