Abstract (en)

The present invention relates to the use of oxide ceramic materials or metal ceramic compounds, which have superconducting properties or can be converted to a superconducting state in non-superconducting electrical applications, for example as a material for resistive heaters. The material is selected from alkaline earth cuprate, rare earth alkaline cuprate, iron pnictides and magnesium diboride. The shape body can be obtained by a melt casting process. The material could be used for a heating element an ohmic resistor or an electrode suitable in electrical arc discharged.
