· JVASP-132385· HfO7

HfO₂ is a refractory ceramic compound based on hafnium oxide, valued for its exceptional thermal stability and resistance to extreme environments. It is used primarily in high-temperature applications such as thermal barrier coatings on turbine blades, nuclear reactor components, and advanced optical systems, where its combination of chemical inertness and high melting point outperforms conventional oxides like alumina or yttria-stabilized zirconia in demanding service conditions.

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.
