    Mar 13 2021 · The Differences in Performance between Lightweight and Heavy Alkali-Resistant Castables. Castable refractory materials that can resist the corrosion of alkali metal oxides (such as K2O and Na2O) at medium and high temperatures are called alkali-resistant refractory castables.The composition of this type of castable is similar to the castable combined with ordinary calcium aluminate cement.
