N-12-40223C/KO/85 ABSTRACT OF THE DISCLOSURE An aluminum oxynitride-containing refractory, a refractory for a sliding nozzle, and a nozzle for continuous steel casting are disclosed. The aluminum oxynitride- containing refractory comprises at least 3 parts by weight of aluminum oxynitride and 0.5 to 60 parts by weight of carbon and/or a carbonaceous compound, the balance being other refractory substance. This refractory is excellent in corrosion resistance against slag, particularly FeO and also in thermal impact resistance. Thus its life time is satis- factorily quite long.
