· JVASP-101165· LiTa2O6

Lithium tantalate (LiTa₂O₆) is an inorganic ceramic compound combining lithium, tantalum, and oxygen, belonging to the family of mixed-metal oxides with high density and thermal stability. This material is primarily used in advanced optoelectronic and electro-optic devices, particularly in integrated photonics, acousto-optic modulators, and frequency-conversion applications where its crystalline properties enable precise control of light and acoustic waves. Lithium tantalate is valued in telecommunications and precision instrumentation for its ability to operate across wide wavelength ranges and temperature windows, though it is less common than its sister compound lithium niobate in general applications and is often selected when tantalum's specific refractive and piezoelectric properties offer performance advantages or when compatibility with existing tantalum-based processing is required.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
