· JVASP-112602· Ca3Ga3Ge3O14

Ca3Ga3Ge3O14 is a rare-earth-free oxide ceramic compound belonging to the langasite family of materials, characterized by its ordered crystalline structure combining calcium, gallium, and germanium oxides. This material is primarily investigated in advanced electronics and photonics research, particularly for piezoelectric and acousto-optic applications where its non-centrosymmetric crystal structure enables functional responses to mechanical stress and electromagnetic fields. While not yet widely commercialized compared to conventional piezoceramics, langasite-family compounds offer potential advantages in high-temperature stability, radiation resistance, and piezoelectric coupling, making them candidates for specialized sensor and actuator systems in extreme 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.
