Beschreibung
Zusammenfassung:	Provided is a refractory product which is not impregnated with pitch or the like, wherein it has higher corrosion-erosion resistance and thermal shock resistance as compared to a refractory product subjected to pitch or the like-impregnation treatment. The refractory product which is not impregnated with tar or pitch is characterized in that, in terms of values of physical properties of a sample of the refractory product as measured after heat-treating the sample in a non-oxidizing atmosphere at 1200°C: an apparent porosity is 7% or less; a total void volume of pores having a pore diameter of 1 µm or less is 80% or more of an integrated void volume of pores of the entire sample of the refractory product; and a gas permeability is 50 × 10-17 m2 or less.
