A ceramic composition, for shaped articles having about 0.45 to about 5.5 percent of an organic water-soluble binder which has a thermal decomposition temperature of about 100 to about 500 DEG C and a viscosity of less than about 10,000 poises at 20 DEG C, about 1.5 to about 4.0 percent of a starch which has a thermal decomposition temperature of about 250 to about 535 DEG C where the thermal decomposition temperature of the binder and the starch are at least about 50 DEG C apart, about 1.5 to about 3.5 percent cellulose, about 0.5 to about 2.0 percent of a dispersant, and about 7 to about 11 percent water, and about 75 to about 89 percent of a high temperature refractory material such as stabilized zirconia. The composition is de-aired, formed into a shape, and fired to produce a ceramic structure. |
