To obtain a higher oxidation inhibiting effect and to control lowering of anti-spalling property in the case of using together with metallic powder and boride as an oxidation inhibitor for a basic refractory containing carbon used for a steel-making furnace, etc.

The basic refractory containing carbon is made by adding Al powdery of 0.5-6 mass%, Mg powder of 0.2-3 mass% and the boride of 0.1-2 mass% to a blending material, main ingredient of which are magnesia raw material and carbon raw material. It is preferable that a ratio of Al/Mg is 1-15, and BN is preferable as the boride.
