· TmHfO3

TmHfO3 is a rare-earth hafnate ceramic composed of thulium and hafnium oxides in a perovskite-like crystal structure. This material is primarily of research and developmental interest for high-temperature applications, particularly in thermal barrier coatings and advanced refractory systems where exceptional thermal stability and chemical resistance are required. TmHfO3 belongs to the family of lanthanide hafnates, which are gaining attention as potential alternatives to conventional thermal barrier materials in aerospace and energy applications due to their ultra-high melting points and phase stability at extreme temperatures.

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.
