· Gd2O3

Gadolinium oxide (Gd₂O₃) is a rare-earth ceramic compound widely used as a high-k dielectric material in microelectronics and as a thermal barrier coating in aerospace applications. It is valued for its wide bandgap, high melting point, and low thermal conductivity, making it essential in advanced semiconductor gate dielectrics, optical devices, and extreme-temperature protective coatings where conventional oxides (such as SiO₂) cannot perform adequately.

Export Control

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.
