Rheological properties of alumina ceramic slurries for ceramic shell-mould fabrication
Abstract
This research is about the properties of ceramic slurries prepared from hydrous nano-alumina-based binder and a corundum matrix used for fabricating the prime coat of ceramic shell moulds. Solid-state alumina powders with different granulations were used. The modification of the technological properties of the prepared slurries was based on additions of a polyacrylic binder with different amounts of polymer with respect to the alumina for different powder ratios. The slurries were prepared and tested in a mechanical mixer. During the slurry preparation (within 96 h), the plate weight, Zahn cup 4# viscosity and dynamic viscosity were controlled. The morphology and chemical properties of corundum powders and polymer were characterized with SEM and powder-grain-size distribution. The obtained results of the corundum-based ceramic slurries indicate that the application of a polymeric binder with various concentrations based on nano-alumina oxides causes different properties in comparison to the other commonly used binders.
