Abstract
A resistor, which is solidified from a melt, is provided for a refractory shaped body, and includes a refractory mineral metal-oxide main component having elasticizers a general formula A B O in an amount so that solubility of the main component for the elasticizer is exceeded with the elasticizers providing precipitation areas in the main component. The resistor is produced by a joint melting of the main component and the oxides which form the elasticizers. A process is provided for the production of the resistor.
