Carbon dioxide is the oxide, cerium deposits of cerium, for CeO2 patent in the combining power of this for + 4 price, have strong oxidizing, white or yellowish-white solid, soluble in water. The effect of the carbon dioxide is 172.115 g/quality Moore mol. Melting point 2400 ℃ 3500 ℃, the boiling point. Carbon dioxide by trioxide deposits of cerium oxide and system: 2 and 4 CeO2 Ce2O3 + O2. Carbon dioxide can and sulfuric acid reaction, cerium sulfate cerium (IV) generation and water. Under the high temperature and carbon monoxide cerium dioxide oxidation reduction reactions: 4 CeO2 + 2 CO and CO2 ↑ Ce2O3 2 + 2.
Ce make a + 3 price oxide trioxide cerium (Ce2O3), but under room temperature, atmospheric carbon dioxide is the most stable cerium deposits of the compounds.
Is tasted for white heavy powder or cube crystallization, not tasted for light yellow or even pink to red brown (because contain trace la, pr, etc.). Hardly soluble in water and acid. The relative density of 7.3. Melting point 1950 ℃. Toxic, half of the lethal dose (rats, classics mouth) about 1 g/kg.
