Abstract:
Filtration is a basic operation frequently used in ceramic industries. Ceramic articles can be shaped using appropriate molds with or without pressure application. In this study, plastic molds with filter properties, high porosity and good permeability, are manufactured by using acrylic polymer powders. Furthermore the pore sizes hence permeability is adjusted by using different particle sizes of these powders. Also a porous open-pore, hardened plastic composition for low pressure slip casting process is manufactured by subjecting a water in oil emulsion to hardening.Pressure slip casting process requires coarser pores while slip casting process requires fine pores like plaster. The achieved pore sizes are 20-40 ìm for molds which can be used in high pressure slip casting and 3-5 ìm for molds which can be used in low pressure slip casting.
