摘要：

The effect of technological factors (composition, temperature, and holding time) on pore structure, gas permeability, and specific Surface of specimens molded from graphite-containing refractory Mixtures is studied. Dense refractories based on crucible and muffle Mixtures can be prepared at 1100-1400degreesC using a silica sol binder. Heat treatment of the refractories at higher temperatures (about 1600degreesC) is not recommended because of the sharp increase in open pore size, which may lead to degradation of performance characteristics.
