Abstract

Disclosed herein are green bodies comprising at least one ceramic-forming powder; at least one binder; and at least one cross-linked starch present in an amount of at least about 20% by weight as a super addition. Further disclosed herein is a method of making a porous ceramic body comprising mixing at least one ceramic-forming powder, at least one solvent such as water, at least one binder, and at least one cross-linked starch present in an amount of about 20% by weight as a super addition to form a batch composition; extruding the batch composition to form a green body; drying the green body; and firing the green body to form a porous ceramic body. Also disclosed herein are methods of screening a green body for making a porous ceramic body.
