Abstract

Materials containing a mixture of a binder and a matrix capable of being heated in an electromagnetic field (EMF) and consisting of at least 70 % inorganic substances are used for foundary and other purposes. The matrix materials contain a surface film of a substance that conducts electricity as well as at least 15 % of a transistion element metal in compound form. The transistion element is iron of which at least 50 % is in the divalent state. The main component of the mixture is sand.
