Refractory material, method for producing same, and use thereof

The invention relates to a refractory material which is thermally treated at a temperature of at least 1300 DEG C, preferably 1300 DEG C to 1750 DEG C, such that the material has an acicular structure and a combination of a first phase, a second phase, and a third phase, wherein: the first phase comprises 2-10 wt.% C, < 5 wt.% N, 30-40 wt.% O, 50-70 wt.% Al, and < 5 wt.% Si, based on the total proportion of the first phase, the second phase comprises 1-7 wt.% C, 3-8 wt.% N, 25-35 wt.% O, 55-65 wt.% Al, and < 5 wt.% Si, based on the total proportion of the second phase, and the third phase comprises < 7 wt.% C, 14-28 wt.% N, 10-15 wt.% O, 52-63 wt.% Al, and < 20 wt.% Si, based on the total proportion of the third phase, to a batch for producing the refractory material, to a main part produced from a batch, to a method for producing a refractory material, and to the use thereof.
