High-resolution evaluation of density distribution in green body

Abstract

Pore structure was directly observed by dyeing of fluorescence in pores. The mixture of fluorescence dye and immersion liquid was filled into pores of alumina green body which was thinned previously. Images were obtained by a confocal laser scanning microscope. Several pictures were taken at a specific change of focusing position in the specimen. Three-dimensional pore structure was reconstructed from these pictures in a computer.
