ceramic

· TaInO4

TaInO4 is an ternary oxide ceramic composed of tantalum, indium, and oxygen, belonging to the family of mixed-metal oxides used primarily in electronic and photonic applications. This material is largely in the research and development stage, explored for potential use in optoelectronic devices, photocatalysis, and high-permittivity dielectric applications where the combination of tantalum's refractory properties and indium's semiconducting characteristics offers tunable electronic behavior. The material's significance lies in its potential to enable next-generation electronics and sensing devices where conventional single-oxide ceramics reach performance limits.

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.
