CERIUM SALTS & COMPOUNDS
- CERIUM CARBONATE (Ce2(CO3)3. xH2O)
Cerium Carbonate is water insoluble and has wide range of applications. Cerium source that can easily be converted to other Cerium compounds, such as the oxide by heating (calcinations).
- CERIUM CARBONATE SYNONYMS
- Cerous carbonate hydrate, Cerium(III) carbonate, Diceriumtricarbonate, Cerium(3+) carbonate (2:3), Cerium carbonate (Ce2(CO3)3), Cerium tricarbonate, Carbonic acid, cerium salt
- Molecular Formula: Ce2(CO3)3. xH2O
- Molecular Weight : 460.27
If it is converted to cerium oxide then it can be used for glass polishing. Carbonate compounds also give off carbon dioxide when treated with dilute acids. The numerous commercial applications for cerium include metallurgy, glass and glass polishing, ceramics, catalysts, and in phosphors. If Low purity cerium carbonate is calcined it converts into Rare earth oxide, which is used for polishing application requiring low purity Cerium oxide.
It is considered to be the most efficient glass-polishing agent for precision optical polishing. Cerium Carbonate is a base raw material for high grade Rare Earth oxide based polishing powder andwhen converted, it can be used for polishing glass with Cerium oxide.
