· HfZrO3

HfZrO3 is a mixed-metal oxide ceramic composed of hafnium and zirconium, belonging to the class of high-entropy or dual-cation refractory oxides. This material is of primary interest in advanced semiconductor and high-temperature applications where its thermal stability, chemical inertness, and structural properties offer advantages over single-component alternatives. The hafnium–zirconium combination is explored in gate dielectrics for next-generation microelectronics, thermal barrier coatings for aerospace engines, and solid-state electrolytes for energy storage, where the mixed-cation structure can suppress phase transitions and enhance performance over a wider operating range.

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.
