Abstract
This paper presents the influence of agglomeration upon the flow property of the slurry and dewaxing properties of the greenware for low pressure molding. (Zr, Sn)TiO 4 powder agglomerate was pulverized by a high speed mixer. The agglomeration state was evaluated by tapping density and residual of #350 sieving. The flow property was measured by viscosity and grindmeter scratch. The dewaxing properties were evaluated by pore size distribution, the fraction of residual binder after dewaxing and rejection ratio of greenware due to crack. Pulverization of the agglomerate reduces the thixotoropy of the slurry, contributing to uniform pore size and residual binder distributions. They all contribute to reduce cracks in greenware.
