· JVASP-54803· Ga2Os

Gallium oxide (Ga₂O₃) is a wide-bandgap semiconductor ceramic material that exists in multiple crystal phases, with the monoclinic β-phase being the most thermally stable form. While not yet widely commercialized, Ga₂O₃ is an active area of research for next-generation power electronics and optoelectronic applications, offering superior breakdown field strength compared to conventional semiconductors like silicon and gallium nitride.

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.
