HfTaO3
ceramic· HfTaO3
HfTaO3 is a mixed-metal oxide ceramic compound combining hafnium, tantalum, and oxygen, belonging to the family of refractory oxides and high-dielectric ceramics. This material is primarily of research and developmental interest for advanced dielectric and insulator applications where extreme thermal stability and high-frequency performance are required. It is notable in the context of next-generation gate dielectrics, microelectronics integration, and high-temperature ceramic coatings, where the combined properties of hafnia and tantalum oxide offer potential advantages over single-component alternatives in suppressing leakage currents and maintaining performance at elevated temperatures.

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.
