    摘要: A spalling- and corrosion-resistance refractory which comprises the composition of refractory material consisting of at least one refractory inorganic substance, 1-30% by weight of low melting point metal powder such as aluminum powder having a particle size below 0.5 mm and 2-15% by weight of thermo-setting organic binder such as phenol resin based on the total weight of the refractory material, respectively.The spalling- and corrosion-resistance refractory is prepared by admixing the refractory material, aluminum powder and phenol resin binder, kneading and molding the mixture and finally burning the green brick at a temperature below 800.degree. C.
