A material for refractory shaped bodies or compounds, the material being a pleonaste and/or a spinel of the pleonaste type. In addition to FeOand AlO, the material also includes MgO. The ratio of the iron in the material is calculated as FeO:AlOand ranges from 30:70 to 60:40. The material contains from 20 to 60% by mass of MgO, as based on FeO+AlO.

Synthetic, refractory material for refractory products, and process for producing the product

A material for refractory shaped bodies or compounds, the material being a pleonaste and/or a spinel of the pleonaste type. In addition to FeO and Al O , the material also includes MgO. The ratio of the iron in the material is calculated as Fe O :Al O , and ranges from 30:70 to 50:40. The material contains from 20 to 60% by mass of MgO, as based on Fe O &plus;Al O .

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.
