Cerium oxide usually appears as a yellow powder. It is insoluble in water and moderately soluble in strong mineral acids. CeO2 is slightly hygroscopic and will absorb small amounts of moisture and CO2 from the atmosphere.

Laboratory Purpose:

With careful and highly advanced process, we sell high purity Cerium Oxide which is widely used in Schools, Universities, Colleges and R& D firms for testing.

Automobile Exhaust Purification Catalyst:

a) In association with other catalysts, ceria can effectively reduce NOx emissions as well as convert harmful carbon monoxide to carbon dioxide. Economically, it also reduces the amount of platinum needed for complete oxidation of NOx and other harmful products of incomplete combustion.

b) It also reduces the sulfur oxide emissions from oil refineries.

c) It is also used as a diesel fuel additive for micro-filtration of pollutants and results in less smoky particulates.

Fluorescent Lighting:

Cerium is an essential component in several of the new generation of phosphors in these tricolor lamps that have made possible more efficient and more compact fluorescent lighting.

Cathode ray Tubes:

Cerium has increased in use as a stabilizer against browning of glass by cathode ray and gamma rays. Most cathode ray tube faceplates use cerium stabilized glass. The nuclear industry has required large quantities of radiation shielding windows which provide very high light transmission without darkening due to formation of color centers.

Carbon Arc Lighting:

Cerium is used in the new discovery of Carbon-arc lighting. Because cerium can be protected within the lamp it can be safely used. Carbon arc lights throw off so much energy that a high-heat capacity is needed. Cerium can take heat easy so cerium is used when the Carbon-Arc lights are illuminating movie sets and projector screens.

Misch Metal:

Cerium is also used in a component called Misch Metal, which is very important in making flint for lighters. The metal reacts steadily with water, readily dissolves in mineral acids and is also attacked by alkali; it will react with most non-metals on heating. The last use of pure cerium is that cerium can aid in the refining of petroleum which is used as an alloying metal to form unique metals used today.
