Project Description

Lanthanum Oxide Nanoparticles


Nano lanthanum oxide is white powder, density 6.51g/cm3, melting point 1430℃、1557℃、1620℃, slightly soluble in water, soluble in acid and generates the corresponding salts.

Exposure to air, it is easy to absorb carbon dioxide and water, and gradually becomes rare earth hydroxide and 50% acetylene and hydrogen as well as hydrocarbon. Burning lanthanum oxide combines with water, emits large amounts of heat.

La2O3 nanoparticle is current conducting just like metal. Nano lanthanum oxide can be made by mixing rare earth metal and a certain carbon into a ball and heat and melt in tantalum crucibles.
