· HfAlON2

HfAlON2 is a hafnium aluminum oxynitride ceramic compound that combines hafnium and aluminum with oxygen and nitrogen phases, forming a hard ceramic material in the refractory oxide-nitride family. This material is primarily investigated in research and advanced applications requiring high-temperature stability, wear resistance, and oxidation protection, particularly in environments where conventional alumina or hafnia alone prove insufficient. HfAlON2 is notable for potential use in extreme-temperature coatings and structural applications where the synergistic properties of hafnium and aluminum phases provide enhanced hardness and thermal resistance compared to single-phase alternatives.

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.
