ABSTRACT:
A ceramic contact sheet and setter tile with controlled porosity is introduced, along with the method for making the same. The amount of porosity is controlled by the volume percentage, particle size, and particle shape of a fugitive phase which can be added to the original refractory material slurry used to fabricate setter tiles and contact sheets. The fugitive phase can be used independently to introduce porosity in setter tiles and contact sheets or in conjunction with partial densification. Since porosity is not solely dependent upon partial sintering, higher porosity levels can be achieved with less impact on subsequent mechanical properties of the resultant refractory material.
