A material mixture for producing a refractory material, comprising:
- spinel;
- zirconium oxide;
- a coarse-grained fraction in a percentage by weight of over 50%;
- and
- a fine-grained fraction,
- wherein the coarse-grained fraction includes coarse grains with dimensions greater than 20 μm and the fine-grained fraction including fine grains with dimensions of less than 20 μm,
- wherein magnesium aluminate spinel and/or sinter spinel and/or fused spinel is/are present as the fine-grained fraction, and
- wherein the fine-grained fraction includes 70 to 100 wt % magnesium aluminate spinel and >12 wt % and up to 30 wt % zirconium oxide.
The material mixture as claimed in claim 4, wherein magnesium aluminate spinel and/or sinter spinel and/or fused spinel is/are present as the coarse-grained fraction.
The material mixture as claimed in claim 4, wherein zirconium oxide is present as the fine-grained fraction.
