ceramic

· JVASP-4035· TaI2O

TaI₂O is an experimental mixed-metal oxide ceramic containing tantalum and iodine, representing an emerging compound in the layered oxide materials family. This material is primarily of research interest rather than established industrial use, with potential applications in advanced electronics, photocatalysis, or two-dimensional material platforms due to its layered crystal structure. Engineers would consider this material for next-generation device applications where tailored electronic, optical, or catalytic properties from rare-metal ceramics are required, though it remains in early-stage development compared to conventional tantalum oxides.

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.
