· JVASP-141192· La2Ta2O9

La2Ta2O9 is a mixed rare-earth/refractory oxide ceramic compound combining lanthanum and tantalum in a layered perovskite-related structure. This material is primarily investigated in research contexts for high-temperature applications and advanced dielectric systems, where its thermal stability and chemical inertness are leveraged to enable device functionality in extreme or demanding environments. Engineers consider this compound when conventional oxides prove inadequate for sustained high-temperature exposure, though adoption remains limited to specialized aerospace, electronic, and materials research settings due to its niche property profile and limited commercial production.

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.
