mischmetal การใช้

• More economically viable alloys using mischmetal instead of lanthanum were soon developed.
• Among his first discoveries / inventions to bear practical fruit was mischmetal.
• Mischmetal is used in the preparation of virtually all rare earth elements.
• It is also called cerium mischmetal, rare earth mischmetal or misch metal.
• It is also called cerium mischmetal, rare earth mischmetal or misch metal.
• Zinc-5 % aluminium mischmetal coatings are designated with an  M.
• Mischmetal, used in making cigarette lighters, historically contained about 5 % praseodymium metal.
• Regular strength Class  A mischmetal thickness weight coated regular strength steel would be designated MA2.
• Historically, mischmetal was prepared from monazite, an anhydrous phosphate of the light lanthanides and thorium.
• Yttrium, often a component of mischmetal, has also been studied as a " possible nodulizer ".
• However, Tallack et al . reported that cerium mischmetal was entirely ineffective against Atlantic spiny dogfish in the Gulf of Maine.
• As a ( minor ) part of mischmetal, samarium is found in " flint " ignition device of many lighters and torches.
• When bastn鋝ite started being processed for rare earth content in about 1965, it too was converted to a version of rare earth chloride, and on to mischmetal.
• Monazite-derived mischmetal typically was about 48 % cerium, 25 % lanthanum, 17 % neodymium, and 5 % praseodymium, with the balance being the other lanthanides.
• Electrolysis of the molten anhydrous chloride ( admixed with other anhydrous halide to improve the melt behavior ) led to the formation of molten mischmetal, which would then be cast into ingots.
• Highly specialized processes, such as those developed by Carl Auer von Welsbach, exploit subtle differences in solubility to separate mischmetal into its constituent elements, with each step producing only an incremental change in composition.
• Stroud ( SharkDefense, 2006 ) and Fisher ( VIMS ) observed captive cownose rays ( " Rhinoptera bonasus " ) changing swim elevation and ignoring blue crab baits in cages that contained neodymium-praseodymium mischmetal.
• Whereas mischmetal  a mixture of rare earth metals containing about 1 % of samarium  has long been used, relatively pure samarium has been isolated only recently, through ion exchange processes, solvent extraction techniques, and electrochemical deposition.
• Nodule formation is achieved by adding " nodulizing elements ", most commonly magnesium ( magnesium boils at 1100 癈 and iron melts at 1500 癈 ) and, less often now, cerium ( usually in the form of mischmetal ).
• A modern ferrocerium firesteel product is composed of an alloy of rare earth metals called mischmetal ( containing approximately 50 % cerium, 25 % lanthanum, and small amounts of praseodymium and neodymium ), plus iron and a small amount of magnesium.
