Hf4 Zr4 O16
ceramic· Hf4 Zr4 O16
Hf₄Zr₄O₁₆ is a mixed-oxide ceramic compound combining hafnium and zirconium oxides in a 1:1 molar ratio, belonging to the family of high-refractory complex oxides. This material is primarily of research interest for high-temperature structural applications where thermal stability and oxidation resistance are critical; it represents an emerging alternative to pure zirconia or hafnia ceramics, leveraging the complementary properties of both constituent oxides to potentially achieve improved phase stability, thermal shock resistance, or sintering behavior. The hafnium–zirconium oxide system is being investigated for aerospace, nuclear, and extreme-environment applications where conventional ceramics face limitations.

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.
