Research progress of new colloidal forming processes for advanced ceramics

The progress of new colloidal forming processes for high performance ceramics developed in Tsinghua University is reviewed. Several new techniques for preparing highly concentrated ceramic suspensions and high-quality green bodies are briefly described, and new ideas about ceramic colloidal forming are introduced. With these new techniques, high performance ceramic parts with high reliability and complex shapes can be mass prepared, by automation, at low cost and after the removal of defects in ceramic green bodies. This may pave the way for the industrialization of advanced ceramics in the near future.
