40-60nm 99% 3N 4N min Samarium fluoride Powder SmF3

40-60nm 99% 3N 4N min Samarium fluoride Powder SmF3

    Method for synthesizing samarium fluoride: Add 1000L of 0.23mol/L samarium chloride solution to the FK3000 enamel reaction tank, heat the samarium chloride solution to 93 ℃, add 300L of 2.5mol/L ammonium bicarbonate solution, complete the precipitation reaction for 3 hours, keep it warm and aged for 1 hour, wash and filter to obtain a mixed precipitation of samarium oxycarbonate and basic samarium carbonate. The weight ratio of samarium oxycarbonate to basic samarium carbonate is 4:1; Add 130L of water to Chemicalbook in a 1000L fluoride conversion tank, precipitate samarium oxycarbonate and basic samarium carbonate into a slurry, and add 40kg of hydrofluoric acid with a weight ratio of 40% to the slurry under stirring. The fluorination temperature is at 20 ℃, and the pH value of the endpoint acidity is controlled to be 1.5-2.0. Continue stirring for 1 hour, wash, filter, and centrifuge the samarium fluoride precipitate, and dry it in a drying kiln at 200 ℃ for 12 hours, The centriole diameter of samarium fluoride product obtained is 30.06 μ m。

    Usage: Anhydrous samarium fluoride belongs to inorganic metal compounds and is widely used: it can be used in semiconductor materials, thermal spraying materials, insulation materials, anti-corrosion materials, thermal barrier materials, fiber doping, laser materials, luminescent materials, doping materials, coating materials, etc.
