Binders for Refractory Castables An Overview SpringerLink
Abstract A binder for refractory castables is a bonding material that bonds a loose powdery mix retains its shape after casting and allows the cast shape to set and harden for handling and further processing A binder also improves sintering as the castables are not compacted during shaping causing poor densification and strength Initially plastic clay was used as a binder for castables
