 Melting point ***7 ℃, ***0 ℃ boiling point, slightly soluble in water, soluble in acid and the generated corresponding salts.Easy absorb air and water and gradually turned into lanthanum carbonate.

Areas of application: lathanum is of very extensive usage, such as applied to piezoelectric materials, electric heat materials, thermoelectric materials, magnetic resistance materials, luminescence materials (LAN powder), hydrogen storage material, optical glass, laser material, all kinds of alloy material, etc. It is also applied to many organic chemical products of preparation of catalysts, light conversion agricultural film also used for weapons,in abroad, the scientists  call it  "super calcium” for its importance for corps.
