Application: mainly used for the production of intermediate compounds of lanthanum, as lanthanum chloride, lanthanum oxide and other raw materials, such as lanthanum compounds.

Preparation:
Carbonate precipitation with lanthanum chloride solution was separated by extraction of raw materials, plus lanthanum carbonate precipitate ammonium bicarbonate.
Safety:
Non-toxic, tasteless, non-irritating, safe, reliable, stable performance, with no water and organic chemical reactions, radioactive ≤0.8Bq / g.
Flammable hazardous characteristics: non-combustible.
Storage features: low temperature dry and ventilated warehouse.
Extinguishing Media: Water.
