Abstract
A fired body and method of making involves compounding powder, binder, aqueous solvent for the binder, surfactant, and non-solvent with respect to at least the binder, the solvent, and the powder, with the addition of an organosilicon compound. The non-solvent is lower in viscosity than the binder combined with the solvent, and the amount of solvent is less than the amount that would be used absent the non-solvent. The components are mixed and plasticized and then shaped into a green body, which is then fired to produce the product body. The organosilicon compound enhances the stiffness in the green body afforded by other non-solvents, and results in increased strength and reduced cracking in the fired body, among other advantages.
