A Technique for the Preparation of Porous Ceramic Materials by Gelcasting Mothod
A technique for the preparation of porous ceramic materials by gelcasting mothod is studied using a water-soluble epoxy resin combined with a amine hardener.The increase in the volume and rheological behavior of slurry,TGA and DSC of the green bodies are investigated.The influence of solid content on the relative density,the cell size distribution and the compressive strenghth is studied.The experimental results show that in the measurable shear rate range the rheology of slurry exhibt a shear thinning behavior,the relative density increase with the solid content,with the decrease of the relative densities the cell size increase.The compressive strength increased exponentially with the increase relative density,and the exponent,m,is 1.094.
