High Purity 99.999% Lanthanum Oxide La2O3 CAS 1312-81-8 For Ceramic Capacitor
Name: Lanthanum oxide CAS: 1312-81-8
Molecular formula: La2O3 Molecular weight: 325.81
Description: The rare earth chloride solution after cerium removal uses the neutral phosphine extractant dimethylheptyl methylphosphonate (P350), and the P350-kerosene system is used for 35 to 38 levels of extraction to separate lanthanum from other rare earths. The solution was neutralized with ammonia water, oxalic acid was precipitated, and then filtered and burned to obtain a finished Lanthanum oxide product.
