Molecular formula: Pr6O11
Appearance: Praseodymium oxide is black or dark brown powder. 
Purpose: Preparation of praseodymium yellow raw materials for ceramic glaze color. Used as coloring agent in glass industry, with green, but imitation gems. For the production and preparation of metallic praseodymium samarium, praseodymium, cobalt permanent magnetic alloy material, and yellow pigment in ceramics. 


English alias: Oxide Lanthanum
Chemical formula: La2O3
Relative molecular weight: 325.8091
CAS number: 1312-81-8
EINECS number: 215-200-5
Melting point: 2217
Water soluble: Slightly soluble in water
Density: 6.51g/cm3
Property description: 
Products should be white crystals. Product clean, no obvious mechanical inclusions. 
Packing: 1000 kg ton bag. 
Product application: 
1 used in the manufacture of special alloy precision optical glass, high refractive index optical fiber board, suitable for camera, camera, microscope lens and advanced optical instrument prism, etc. ., 
2 used in the manufacture of ceramic capacitors, piezoelectric ceramic doped agent and X - ray luminescent materials, such as lanthanum bromide. 
3 used as a catalyst for a variety of reactions, such as the oxidation of carbon monoxide when doped with cadmium oxide reaction, the reaction of carbon monoxide hydrogenation to produce methane. 
4 impregnated lithium oxide or zirconium oxide (1%) lanthanum oxide can be used in the manufacture of ferrite magnets. 
5 is a very effective selective catalyst for the oxidative coupling of methane to ethylene and ethylene. 
6 for improving the temperature dependence and dielectric properties of barium titanate (BaTiO3), strontium titanate (SrTiO3) ferroelectric, and the fabrication of fiber optic devices and optical glass. 
Preparation method: 
Carbonate precipitation method to the extraction separation of lanthanum chloride solution as raw materials, ammonium bicarbonate and precipitation of lanthanum carbonate, by heating, aging, washing, separation, and burning of lanthanum oxide. Can be prepared by heating the decomposition of lanthanum oxalate. 
Security: 
Products non-toxic, tasteless, no stimulation, safe and reliable, stable performance. But with the chemical reaction of water, hydrogen production, easy to ignite. 
Flammable risk characteristics: Non combustible. 
Transportation characteristics: Transportation should prevent insolation, rain, high temperature resistant. Should stay away from the fire, heat, high temperature zone. Extinguishing agent: Dry powder fire extinguisher.
