Advantage: Bear the heat, the anti - decay, refractoriness under load is high. It is suitable to be used in different high temperature kiln stove.
After the specimens were sintered, with the decrease of the content of mullite in matrix the bend strength decreased, but the refractoriness under load increased.
The bend strength and the refractoriness under load of the specimen in which mullte was used as a part of coarse particle were all higher than that the specimen with mullte the coarse particle.
Test method for pyrometric cone equivalent(refractoriness) of refractories
