properties

Cerium (III) carbonate and its pentahydrate are white solids that are practically insoluble in water. The pentahydrate has an orthorhombic crystal structure with the space group Pbnb (space group no. 56, position 5) . If the anhydrate is boiled in water, Ce (OH) (CO ₃ ) can be formed. When heated to over 500 ° C, the compound decomposes into ceria , carbon monoxide and carbon dioxide . Template: room group / 56.5

use

Cerium (III) carbonate is used in the manufacture of cerium (III) chloride and incandescent lamps.
