Refractory material, method for producing same, and use thereof

Abstract

The invention relates to a refractory material which is thermally treated at a temperature of at least 1300° C., preferably 1300° C. to 1750° 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.
