Product Description
Lanthanum oxide is a white amorphous powder. The density of 6.51g/cm3. The melting point of 2217 DEG C. Boiling point is 4200 ºC. Slightly soluble in water, soluble in acid and generates the corresponding salts. Exposed to air is easy to absorb carbon dioxide and water, gradually become lanthanum carbonate. Burning lanthanum oxide hydrate release a lot of heat.
The main application areas for the manufacture of special alloy precision optical glass with high refractive index, optical fiber board, suitable for the camera, camera, microscope lens and senior optical prisms. Also used in the manufacture of ceramic capacitor, piezoelectric ceramic doping agent and X ray luminescence materials with lanthanum oxide powder. Ceriu m lanthanum phosphorus ore by extraction or by burning or l anthanum nitrate and lanthanum carbonate. Can also be made by lanthanum oxalate heating decomposition can be prepared. Used as catalysts for many reactions, such as doped ca dmium oxide catalytic carbon mon oxide oxidation reaction, doped palladium catalytic hydrogenation of carbon mon oxide to generate metha ne reaction. Leach into the lithium oxide or zirconium oxide lanthanum oxide ( 1% ) can be used for manufacturing ferrite magnet. Oxidative coupling of metha ne generation is ethan e and ethylene very effective selective catalyst. For the improvement of barium titanate, strontium titanate ( BaTiO3 ) ( SrTiO3 ) of the temperature dependence of ferroelectric and dielectric properties, as well as the manufacture of fiber optics and optical glass.
Mainly used in the manufacture of precision optical glass, optical fiber. Also used in the electronics industry for ceramic capacitor, piezoelectric ceramics doped with agent. Also used for preparing lanthanum boride raw material, the separation of petroleum refining catalyst. Lanthanum oxide handling and storage
Matters needing attention : closed operation, overall ventilation. The operator must go through specialized training, strict compliance with operating procedures. Proposed operators wear for filter type respirators ( half mask ), wear safety glasses, wear anti-static overalls, wear oil resistant rubber gloves. Away from fire, heat, smoking is prohibited in the workplace. The use of explosion-proof ventilation systems and equipment. To prevent steam leakage in the air of workplace. Avoid oxidizing agents, acids, alkali contact. When the filling velocity should be controlled, and a grounding device, prevent the accumulation of static electricity. When moving to light light unloading, prevent damage to packaging and containers. Equipped with the appropriate variety and quantity of fire-fighting equipment and emergency treatment equipment for leakage. May be left empty containers of hazardous material.
