High Purity 99.999% Lanthanum Oxide La2O3 CAS 1312-81-8 For Ceramic Capacitor

Lanthanum oxide is an important rare earth metal oxide that appears as a white powder. It is slightly soluble in water, but soluble in solvents such as acid and ethanol. In the air, lanthanum oxide readily absorbs carbon dioxide and water, and is gradually converted to lanthanum carbonate. Lanthanum oxide is widely used, especially in the glass, ceramics and electronics industries. It is often used in the manufacture of precision optical glass, optical fiber and ceramic capacitors. In the field of electronics, lanthanum oxide is also a key material for the manufacture of piezoelectric ceramic adducts. In addition, it is also used as a catalyst in a variety of chemical reactions, such as promoting the oxidation of carbon monoxide and the reaction of carbon monoxide hydrogenation to methane.

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 dimethylhepty l 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.
