Abstract
A permeable refractory body, characterized in that it consists of a refractory grain having a mesh size of 4 to 90, and a silicon oxynitride binder therefor, said body having a porosity, represented by the flow ratio "f" at the drop of "p" pressure, of f/p of at least about 0.3, in which f is measured in liters per hour per cm2, and p is measured in mm of water per mm of thickness of said body, the pores being of said body essentially free of filamentary monocrystals of silicon nitride.
