The optimization of dispersant content in alumina castable
In this research two series of ultra-low cement high alumina refractory castables containing 0 and 0.4 wt. of nano-titania were prepared using different amounts of polycarbonic acid (DOLAPIX FF 26) as a dispersant. Several characteristics including microstructure flowability mechanical strength bulk density and apparent porosity of the samples were analyzed. With addition of nano-alumina particles the self-flow value and working time tends to decrease due to high surface area of nano-alumina particles. By use of 1 wt. nano-alumina content in the castable composition the alumina self-flowing castable with adequate working time can be obtained according to standard values of self-flowing castables.
