Abstract
An energy-storage element, i.e. a body of high heat capacity capable of storing thermal energy and especially electrothermal energy, consists of 50-95% magnesium oxide, 5-50% iron oxide and a chemical binder, the mean particle size of the magnesium oxide lying between 0.1 and 4 mm and that of the iron oxide below 0.5 mm, preferably between 0.01 and 0.2 mm.
