oxide, ceric oxide, ceria, or sometimes simply cerium oxide or cerium
dioxide, is a pale yellow-white powder, CeO2. It is used in ceramics, to
polish glass, and to sensitize photosensitive glass.
Ceria is used
in the walls of self-cleaning ovens as a hydrocarbon catalyst during the
high-temperature cleaning process.
of cerium oxide with a narrow size distribution (615%) are prepared by
mixing cerium nitrate solution with an ammonium reagent.
has been prepared and used to decrease the sintering temperature from 1500
°C to 1200 °C.
cerium oxide (ceria, CeO2) powder was synthesized by a thermochemical
process and tested for its feasibility as an oxygen gas sensor. Procedures
of the process consisted of the preparation of a precursor powder by spray
drying a ceriumnitrate solution and the heat treatment in air to evaporate
volatile components from the precursor, thereby forming nanostructured
oxide is an excellent catalyst for redox reactions and is used as an
important additive in the three-way catalyst (TWC) for automotive exhaust
nanoparticles protect against the progression of cardiac dysfunction and
remodeling by attenuation of myocardial oxidative stress, ER stress, and
inflammatory processes probably through their autoregenerative antioxidant
In U.S. and
in the countries of Europe and Asia to provide worldwide patent protection
and to differentiate unique technology of the recently-developed CMP
slurry based on self-activated cerium oxide particles.
Research and Development has led to the launch of a new soft-settling,
premium grade, Cerium Oxide polish, Unicer 636, which can enhance
productivity while cutting machine maintenance downtime, and reducing the
possibility of 'sleeking'.
