· ErHfO3

ErHfO3 is an erbium hafnium oxide ceramic compound belonging to the rare-earth hafnate family. This material is primarily explored in advanced thermal barrier coating (TBC) systems and high-temperature structural applications where exceptional thermal stability and chemical inertness are required. ErHfO3 represents a research-stage material offering potential advantages over conventional zirconia-based ceramics in extreme-temperature environments, particularly in aerospace and power generation sectors where superior phase stability and lower thermal conductivity are beneficial.

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.
