Cerium(III) Carbonate
Cerium(III) Carbonate Ce2(CO3)3, is the salt formed by cerium(III) cations and carbonate anions. It is a water insoluble Cerium source that can easily be converted to other Cerium compounds, such as the oxide by heating (calcin0ation). Carbonate compounds also give off carbon dioxide when treated with dilute acids.
high grade Lanthanum hydroxide Hydrate
Lanthanum Hydroxide
Lanthanum Hydroxide is a highly water insoluble crystalline Lanthanum source, which can be obtained by adding an alkali such as ammonia to aqueous solutions of lanthanum salts such as lanthanum nitrate.   This produces a gel-like precipitate that can then be dried in air. Lanthanum hydroxide does not react much with alkaline substances, however is slightly soluble in acidic solution. It is used compatibly with higher (basic) pH environments.
