Selection of dispersants for high-alumina zero-cement
· As a result of their markedly high solid loading (>80 vol. ) refractory castables usually display very short interparticle distances. Therefore short-chain molecules capable of providing an electrical double layer sufficiently thick to prevent particle coagulation tend to be suitable dispersants for zero-cement high-alumina castables.
