ceramic

· TaLaO3

TaLaO₃ is a mixed-metal oxide ceramic compound combining tantalum and lanthanum oxides, belonging to the family of high-refractive-index and ferroelectric ceramics. This material is primarily investigated in research contexts for optoelectronic and photonic applications, where its optical transparency, high dielectric constant, and thermal stability make it potentially valuable for integrated photonics, optical waveguides, and next-generation dielectric layers in microelectronic devices. Compared to conventional silicates and aluminas, tantalum-lanthanum oxide systems offer superior refractive indices and tunable dielectric properties, positioning them as candidates for miniaturized optical components and advanced thin-film applications where conventional materials 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.
