Application:

1. Glass (TV glass) glass industry used to do a bleaching agent and clarifying agent.
2. For the preparation of the car in the chemical industry autocatalyst, PVC stabilizers.
3. Also for the synthesis of naphthalene cerous do paint driers.
4. metallurgical industry used to do ductile iron smelting nodulizer cerium silicon alloy, also can be used as cerium-rich rare earth ferrosilicon alloy smelting raw materials. 5. additive plating technology used to do.
Preparation:
Solvent Extraction: mixed light rare earth carbonate ore by roasting, sulfuric acid leaching, get rare sulfuric acid leaching solution, adding potassium permanganate, borax, with di (2-ethylhexyl) phosphoric acid (P204) - Tributyl phosphate (TBP) kerosene solution as extraction agent, separation of cerium and other trivalent rare earths. Back-extracted with sulfuric acid, sodium sulfate raffinate generated double salt precipitation, filtration, washing, addsodium hydroxide transformation, filtration, drying cerium hydroxide.
