Our advantage:
1. Competitive price of Rare Earth Lanthanum oxide comes from factory directly.
2. We only use high quality materials, so our high purity Lanthanumoxide La2O3 does NOT have radioactivities and have very little impurities.
3. OurLanthanum oxidepowder is more ultrafine and better than other factories' who use carbonic acid method or chemical method to get the Competitive price of Rare Earth Lanthanum oxide
