Ba3NbGa3Si2O14 is a complex oxide ceramic compound belonging to the langasite family of materials, known for exceptional piezoelectric and electro-optic properties. This material is primarily of research and emerging industrial interest for high-temperature acoustic and frequency control applications, particularly where conventional piezoelectric ceramics (such as lead zirconate titanate) would fail due to thermal constraints or environmental sensitivity. Its langasite-type structure makes it candidates for advanced sensor systems, RF filters, and precision oscillators operating in extreme temperature environments.

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.
