ABSTRACT

One of the most popular and widely used fabrication processes for making thin ceramics is the tape casting technique, which is used to produce porous tapes for studying moisture content in gases. Pore size and distribution have been analyzed from an SEM picture by an image analyzer. These data were then compared with the uniaxially pressed disc-type sample and a sample prepared by porous, thick film paste. Compared to the other techniques used, pore size distribution could be much more accurately controlled using tape casting. This distribution, in turn, has a large controlling effect on the range and sensitivity of the measurement of gas moisture.
