Lanthanum Oxide Powder
Lanthanum oxide is a solid white powder in appearance. It is easy to absorb water and absorb air. It should be stored in a dry place instead of open air. It should be protected from rain and dampness during transportation.
Applications of Lanthanum Oxide Powder
Lanthanum oxide can be used to manufacture precision optical glass, optical fiber, ceramics, catalyst, electronic industry, ceramic capacitor, piezoelectric ceramic additive, the raw material for preparing lanthanum borate, and catalyst for petroleum separation and refining. In addition, lanthanum oxide can also be used to manufacture optical glass, laser materials, piezoelectric materials, electrothermal materials, thermoelectric materials, magnetoresistive materials, luminescent materials, hydrogen storage materials, various alloy materials, catalysts for organic chemical products, rare earth fertilizer, etc.
