Cerium(IV) oxide, 20% in H2O, nanoparticle dispersion, high pH, <5.0nm APS Number Weighted


Chemical Properties

Formula Weight
Storage & Sensitivity
Ambient temperatures.
Very low water solubility (<0.123 ?g/L at 20°C) and soluble in concentrated mineral acid.


The 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 photochromic 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 .
