Abstract
A method for forming an article involves forming a mixture of components of powder materials, organic binder, solvent for the binder, non-solvent with respect to at least the binder, the solvent, and the powder materials, wherein the non-solvent is lower in viscosity than the binder combined with the solvent, and an agent for retarding the oxidation of the organic components. The components are mixed and plasticized, and shaped into a green structure which is then fired to impart strength and form the product article. The product article has fewer cracks than it would have absent the oxidation-retarding agent.
