Effect of mixing condition of additives on the solidification of green body by gelcasting method

In order to find out conditions for fabricating green body with no defect in gelcasting method, effect of mixing conditions of additives on solidification process of ceramics slurry has been examined in this study. Flow pattern of alumina slurry is deduced by considering actual power consumption of...

description In order to find out conditions for fabricating green body with no defect in gelcasting method, effect of mixing conditions of additives on solidification process of ceramics slurry has been examined in this study. Flow pattern of alumina slurry is deduced by considering actual power consumption of an agitation mixer as well as Reynolds number of agitation calculated, and then compared with observation of solidified green body. The effects of mixing condition is described as a function of the rotation speed and related to flow regimes such as laminar, transition and turbulent flow. It has been found that the boundary between the transition and turbulent flow region is the most suitable for gelcasting method.
