· TmPaO3

TmPaO3 is an experimental mixed-metal oxide ceramic composed of thulium and protactinium oxides in a perovskite-type structure. This material is primarily of research interest in nuclear materials science and solid-state chemistry, where rare earth and actinide oxides are studied for their unique electronic, thermal, and radiation-tolerance properties. While not widely deployed in commercial applications, compounds in this family are investigated for potential use in advanced nuclear fuel systems, radiation shielding, and high-temperature structural ceramics in extreme environments.

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.
