· ZrHfO3

ZrHfO3 is a mixed-metal oxide ceramic composed of zirconium and hafnium oxides, belonging to the refractory oxide family. This material is primarily explored in research and advanced applications requiring high thermal stability, corrosion resistance, and chemical inertness—such as nuclear fuel cladding, aerospace thermal barriers, and high-temperature structural components. While not yet widely established in mainstream industrial production compared to single-phase ZrO2 or HfO2, the dual-metal composition offers potential advantages in tailoring thermal conductivity, phase stability, and radiation tolerance for extreme-environment engineering.

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.
