		The metals usually occur together in minerals as their oxides (rare earths) and are somewhat difficult to separate because of their chemical similarity.
		Misch metal is an alloy of the cerium metals often used in lighter flints, in alloys with other metals (especially magnesium), and to remove residual gases in the manufacture of vacuum tubes.
		Individual metals may be isolated as their compounds by ion exchange methods, solvent extraction, or fractional crystallization, and chemically or electrolytically reduced to the pure metal.

	Applications
		Metallic cerium is found chiefly in an alloy with iron that composes the flints used in cigarette lighters.
		The metal's oxide is used in the glass of color-television tubes to increase contrast, and in lasers.
		The metal is used, with small amounts of other rare earth metals, in magnesium alloys and in misch metal, an alloy used for cigarette-lighter flints and as a deoxidizer in alloys and vacuum tubes.

		Misch metal can be obtained at a lower cost than pure elements such as lanthanum, cerium or the like, and is thus practical.
		As the Misch metal, a commercially available alloy of 45 to 50% by weight of cerium, about 30% by weight of lanthanum, and the balance being comprised of neodymium, promethium, samarium, etc. was used.
		Relations between the amounts of antimony and Misch metal and the discontinuity ratio were investigated, and the results are given in FIG.

	rare earth metal -- Britannica Concise Encyclopedia - Your gateway to all Britannica has to offer!
		The rare earths themselves are pure or mixed oxides of these metals, originally thought to be quite scarce; however, cerium, the most plentiful, is three times as abundant as lead in the Earth's crust.
		These metals are similar chemically because their atomic structures are generally similar; all form compounds in which they have valence 3, including stable oxides, carbides, and borides.
		As purer rare-earth metals are produced, it is increasingly clear that many of their properties are extremely sensitive to small amounts of impurities.

		The effects of restoration and certain elements, nitrogen, sulphur, calcium and Misch metal, on the hot ductility of austenitic, high-alloyed austenitic and duplex stainless steels have been investigated by means of hot rolling, hot tensile, hot bending and stress relaxation tests.
		However, the effect of sulphur can be eliminated by reducing its content and by calcium or Misch metal treatments that significantly increase the number and decrease the average size of the inclusions.
		It seems that the desulphurisation capacity of an element is the most important property for assessing its usefulness in reducing the detrimental influence of sulphur.
