Abstract: At the end of the 70s', with a great upsurge in ceramic heat engine, fine ceramics was paid great attention to by all countries, research departments and industrial circles in the world. In the 90s', high performance structure ceramics were confronted with many difficulties, of which forming processes of intricate shape structure ceramics are the key link on preparing high performance ceramic parts and materials. In this paper, development on recent colloidal forming processes of fine ceramics are reviewed. It is noted that consolidation in - situ forming techniques are an important link for ensuring the uniformity of green bodies and increasing the reliability of ceramics. Finally, key techniques of forming processes needed to strengthen and resolve in the future are emphasized.

Keywords: fine ceramics, consolidation in - situ techniques, forming processes
