Abstract
The present invention relates to methods for the formation of ceramic bodies. Methods of the invention involve processing ceramic-forming compositions to form an integrally self-supporting or stabilized structure, which may then be sintered to give the full-density ceramic product. Methods of the invention may also involve densification of the ceramic body. In one set of embodiments, the volume of the integrally self-supporting structure is reduced by at least 20%. The present invention may produce ceramic bodies having greater strength and durability, since the ceramic-forming compositions may be low in viscosity and may be homogeneously blended, decreasing the possibility for defects.
