The invention relates to a granular, refractory mineral elasticizing granulate for refractory products, in particular for basic refractory products. The minerals consist of mono-phased fused spinel mixed crystal or multi-phased fusion products of the ternary system MgOFe.sub.2O.sub.3Al.sub.2O.sub.3 of the composition range MgO: 12 to 19.5, in particular 15 to 17 wt.- %, Remainder: Fe.sub.2O.sub.3 and Al.sub.2O.sub.3 in a quantity ratio range of Fe.sub.2O.sub.3 to Al.sub.2O.sub.3 between 80 to 20 and 40 to 60 wt.- %.

Starting from an MgO content between 12 and 19.5 wt.- %, the respective mixed crystals have an Fe.sub.2O.sub.3 and Al.sub.2O.sub.3 content in a solid solution out of the limited ranges respectively indicated thereof, such that a total composition of 100% is obtained. In addition, the invention relates to a method for production of the elasticizing granulate and to the use thereof.

The invention concerns a batch for manufacturing a refractory ceramic product, a method for applying a gunning mass or casting mass to a surface, a method for manufacturing a refractory ceramic product, a refractory ceramic product as well as the use of a batch.
