· LuHfO3

LuHfO3 is a rare-earth hafnate ceramic compound combining lutetium and hafnium oxides, representing an advanced refractory and high-k dielectric material under active research development. This material is primarily investigated for next-generation microelectronic gate dielectrics, high-temperature structural applications, and thermal barrier coatings, where its combination of high dielectric constant, thermal stability, and chemical inertness offers advantages over conventional oxides in extreme environments and scaled semiconductor devices.

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.
