· TiHfO2N

TiHfO₂N is a ternary ceramic compound combining titanium, hafnium, oxygen, and nitrogen—representing a high-entropy or mixed-metal oxynitride in the refractory ceramic family. This material is primarily in the research and development phase, explored for applications requiring extreme thermal stability, wear resistance, and oxidation protection at elevated temperatures. Its appeal lies in combining the thermal durability of hafnium-based ceramics with titanium's strength and nitrogen's hardening effects, making it a candidate for next-generation thermal barrier coatings, cutting tools, and high-temperature structural applications where conventional single-phase ceramics fall short.

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.
