About Lanthanum Oxide
About Lanthanum Oxide

The finished product of Lanthanum oxide is prepared by the extraction separation technology with P350 kerosene system through 35~38 stage extraction separation to separate lanthanum from other rare earths. The raffinate containing lanthanum is neutralized by ammonia water, precipitated by oxalic acid, filtered and burned. It is prepared by extracting phosphate cerium lanthanum ore or burning Lanthanum carbonate or Lanthanum(III) nitrate. It can also be made by heating and decomposing lanthanum Oxalate.
