LaHfO3
ceramic· LaHfO3
LaHfO3 is a rare-earth hafnate ceramic compound combining lanthanum and hafnium oxides, belonging to the perovskite family of high-refractive-index materials. This material is primarily investigated for advanced dielectric and optical applications, particularly in gate dielectrics for next-generation semiconductor devices and as a high-k material alternative to traditional silica in integrated circuits. Its high thermal stability, low leakage current characteristics, and compatibility with silicon processing make it a candidate for scaling beyond conventional gate oxide limits in microelectronics, though it remains largely in research and early development stages rather than mainstream production use.

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.
