Uses of Lanthanum Metal Powder

Lanthanum metal powder has a larger specific surface area, higher reactivity, and better dispersibility compared to bulk lanthanum metal. Its applications are increasingly expanding in fields such as steel, precision alloys, special metals, and catalysts. Tungsten alloys, molybdenum alloys, and titanium alloys have issues such as low grain boundary strength and brittleness at low temperatures. During their processing, adding lanthanum metal powder and other rare earth metal powders and thoroughly mixing them can utilize the rare earth micro-alloying effect to effectively refine the structure and improve alloy properties.

Other Uses of Lanthanum Powder

1. Used in the production of nickel-metal hydride batteries, which is one of the main applications of lanthanum powder.

2. Mainly used for manufacturing special alloy precision optical glass and high refractive optical fiber plates, suitable for making cameras, cameras, microscope lenses and optical instrument prisms, etc. It is also used in the manufacture of ceramic capacitors, piezoelectric ceramic doping agents and X-ray luminescent materials such as lanthanum oxybromide powder. Extracted from cerium phospholanthanum ore or by ignition

3. Used as a catalyst for various reactions, such as catalyzing the oxidation reaction of carbon monoxide when doped with cadmium oxide, and catalyzing the hydrogenation of carbon monoxide to generate methane when doped with palladium. Lanthanum oxide impregnated with lithium oxide or zirconium oxide (1%) can be used to make ferrite magnets. It is a very effective and selective catalyst for the oxidative coupling of methane to produce ethane and ethylene. Used to improve the temperature dependence and dielectric properties of barium titanate (BaTiO3) and strontium titanate (SrTiO3) ferroelectrics, and to manufacture fiber optics and optical glass.
