	Fisher Scientific UK - Mischmetall in organic synthesis
		Mischmetall is one of the main sorts of mixed rare earths.
		Mischmetall is commercially available as ingots which are easily powered with a rasp.
		This is impossible with most of the pure metal powders (especially cerium and lanthanum), surface of which is rapidly covered with an oxide layer.

	Rare Earths
		When only the general properties of the rare earths is required, mischmetall is an economical alternative.
		Minerals containing rare earths are not especially rare, and the recent demand for rare earths has led to the discovery of new ores.
		As an example of the metallurgical uses, mischmetall was used in the steel alloy for the Alaska crude oil pipline.

		Mischmetall, zinc–copper couple, and Dewarda alloy in the pinacol coupling of aldimines; 92–96
		New cheap reagents for the pinacol type coupling reaction of aldimines such as mischmetall, Zn–Cu couple, and Dewarda alloy are introduced.
		Key words: mischmetall, Zn–Cu couple, Dewarda alloy, imine, pinacol coupling.

	Method of and device for storing and transforming heat and generating cold - Patent 4829772
		A system according to claim 1, including at least one of means for supplying heat to the first container and means for withdrawing heat from the first container.
		Appropriate low-temperature metal-hydride and metal systems in the sense of the present method are those with a hydrogen-dissociation pressure that is lower subject to the conditions of thermal dissociation on the part of the magnesium hydride and higher during its restoration than that of the magnesium hydride.
		At the beginning of every heat-storage cycle the high-temperature reservoir is charged with hydrogen (in the form of magnesium hydride) whereas the low-temperature reservoir is left uncharged (containing the pure alloy).

	Electrochemical cell comprising stable hydride-forming material - Patent 4487817
		Corrosion can be controlled only partly by providing an oxygen-reduction electrode in the cell, as described in German patent specification No. 2,838,857, because lanthanum, at potentials more positive than -2.0 V with respect to a reversible hydrogen electrode, reacts with water according to the reaction equation:
		Mischmetall is a mixture, consisting of more than 50% by weight of Ce, about 25% by weight of La, about 25% by weight of a mixture of other rare-earth metals.
		The exact composition varies according to the place of origin of the material.
