POROUS CERAMIC MATERIALS FOR INVESTMENT CASTING
Methods and compositions for forming porous ceramic articles are provided. The method is forming a composition including liquid siloxanes, ceramic particles, a catalyst, and a pore-former; shaping the composition; curing the composition to form a green body; volatilizing the pore-former before or after curing the composition; and firing the green body. The pore-former is a silicon-bearing agent with an average molecular weight under 1300 grams per mole, or a molecule with a molecular weight under 1,000 grams per mole and a freezing point between -40° C and 25° C that is soluble in the liquid. The composition comprises liquid siloxanes, ceramic particles, a catalyst, and a pore-former, which is an agent with an average molecular weight under 1300 grams per mole or a molecule with a molecular mass under 1,000 grams per mole and a freezing point between -40° C and 25° C that is soluble in the liquid.
