용도The addition of CeO2 to CuO/TiO2 increases specific surface area and inhibits sintering and pore size growth at high temperatures. It is used as an additive in glass industry. Cerium dioxide is mainly used as such or in formulation as a high precision polishing agent for glass products, as catalyst or catalyst support. Polishing and decolorizing glass; opacifier in vitreous enamels and photo chromic glasses; heat-resistant alloy coatings; as a cracking catalyst; as a catalyst for automobile emission control; in ceramic coatings; in phosphors; in cathodes; in capacitors; in semiconductors; in refractory oxides; gemstone polishing, as raw material for the production of glass and ceramics as well as additives in paints and varnishes.
일반 설명Cerium(IV) oxide (CeO2) is a class of rare earth materials which can be synthesized by a variety of methods which include thermal hydrolysis and hydrothermal method. Its properties include a high refractive index, and dielectric constant.
Cerium(IV) oxide may be obtained by heating cerium oxalate, carbonate or other salts at elevated temperatures: Ce2(C2O4)3 + 2O2 → 2CeO2 + 6CO2
