langbeinite การใช้

• Anhydrous double sulfates of ammonium also occur in the Langbeinites family.
• These include Tutton's salts and langbeinites.
• Sulfate of potash-magnesia ( langbeinite ) : Quick potassium source for short-term fix.
• Above this temperature range, langbeinite ( K 2 Mg 2 ( SO 4 ) 3 ) is formed.
• It occurs in association with fedotovite, klyuchevskite, lammerite, nabokoite, atlasovite, langbeinite, hematite and tenorite.
• Double tungstates of the form A 2 B 2 ( WO 4 ) 3 are predicted to exist in the langbeinite form.
• Since gamma rays occur naturally, this radiation induced thermoluminescence can be used to date evaporites in which langbeinite can be a constituent.
• Potassium and ammonium nickel langbeinite can be made from nickel sulfate and the other sulfates by evaporating a water solution at 85 癈.
• For some langbeinites only the cubic form is known, but that may be because it has not been studied at low enough temperatures yet.
• The phosphate langbeinites are insoluble, stable against heat, and can accommodate a large number of different ions, and have been considered for immobilizing unwanted radioactive waste.
• For example cobalt langbeinite shows a broad absorption around 555 nm due to the cobalt 4 T 1g ( F ) ?! 4 T 1g ( P ) electronic transition.
• The Permian Basin is also a major source of potassium salts ( potash ), which are mined from bedded deposits of sylvite and langbeinite in the Salado Formation of Permian age.
• Double sulfates of the composition, where " A " is a univalent cation and " B " is a divalent metal ion are referred to as langbeinites, after the prototypical potassium magnesium sulfate.
