Sažetak
This paper reports the results of studying the stabilization of alumina ceramics suspensions which contain a considerate amount of waste alumina powder. The study focused on the investigation of the influence of different amounts of the commercial dispersant Tiron, binder PVA-poly(vinyl alcohol) and the magnesium spinel as additives for the stabilization of highly concentrated alumina suspensions with 20 wt. % of waste (or secondary) alumina powder. Waste alumina powder is obtained after the green machining in factory production of ceramics. Suspensions with different amount of dispersant, binder and additive were prepared based on the response surface methodology design to optimize the suspension viscosity. The viscosity was used for the suspension stability estimation because it is very simple, rapid and accurate method. The lowest viscosity value of all suspensions was achieved with the addition of 0.05 % Tiron, 0.1 % PVA and 0.2 % magnesium spinel expressed on dry weight basis. The obtained results suggest the waste alumina powder is appropriate for shaping new ceramic products by slip casting method.
