A method of producing a heating element made from molybdenum silicide and alloys thereof, and which includes aluminum oxide on its surface. A material is produced that contains substantially Mo(Si<SUB>1-x</SUB>Al<SUB>x</SUB>)<SUB>2 </SUB>and Al<SUB>2</SUB>O<SUB>3 </SUB>by mixing a mixture of a silicon and molybdenum compound with an aluminum compound. Either of the silicon and molybdenum compounds include Mo(Si<SUB>1-y</SUB>Al<SUB>y</SUB>)<SUB>2 </SUB>and are mixed with one or both of an aluminum compound in the form of Al<SUB>2</SUB>O<SUB>3 </SUB>or Al(OH)<SUB>3 </SUB>and optionally the compounds SiO<SUB>2</SUB>, Si, and MoO<SUB>3</SUB>, or by virtue of the mixture of the silicon and molybdenum compound containing MoO<SUB>3 </SUB>and Al and Si and/or SiO<SUB>2</SUB>. The input components together have a degree of purity corresponding to at least 98%. The mixture reacts exothermically and/or by being sintered, so that exchange reactions take place to form the compounds Mo(Si<SUB>1-x</SUB>Al<SUB>x</SUB>)<SUB>2 </SUB>and Al<SUB>2</SUB>O<SUB>3</SUB>, where x lies in the range of 0.4-0.6.
