Properties of Refractories – IspatGuru

16.12.2016· Properties for chemical stress. Chemical composition – The chemical composition of refractories is of great importance with respect to attack by liquid slags, flue dusts, glass melts and vapours. Based on the behaviour during contact reactions, the refractories can be egorized as (i) acid refractories (silica, silicon carbide, zircon cristobalite, and zircon silie etc.), (ii) basic

Recent advances in silica-alumina refractory: A review

of requirements for the refractory. Since glass in the molten state is quite fluid and tends to go through the refractory pores, the most needed characteristic should be nonporous refractories, and hencefusedrefractoriesareusedinmoltenglasscontactareas [1,6,8].
