Properties of Refractories – IspatGuru

16.12.2016· Refractory materials with high porosity are usually not chosen when they are to be in contact with liquid slag since they can be penetrated as easily. The bulk density is generally considered in conjunction with apparent porosity. It is a measure of the weight of a given volume of the refractory. For many refractories, the bulk density provides a general indiion of the product quality. It
