Mix Design, Properties, and Installation Procedures for Phosphate-Bonded Refractory Castables
Phosphoric acid reacts negligibly with acidic oxides at room temperature and does not undergo hardening; consequently, it is unsuitable for use as a binder in acidic refractory materials. In contrast, phosphoric acid reacts with amphoteric oxides (such as Al₂O₃) at room temperature to form a hard solid, and the reaction rate between them can be … Read more
