Tape casting process was formally applied to industrial production of ceramiccapacitors in 1947， and G. N. Howatt received the franchise in 1952. This wasthe first ceramic patent （Howatt G. N.， 1952） for tape casting for the production. In 1967， an A1203 film was successfully prepared by using tape casting byH. N. Stetson and W. J. Gyurk （Stetson H. N.， et al.， 1967）. In the same year， IBMcorporation announced that layer packaging materials for use of computer hadbeen made by tape casting technology （Schwartz B.， et al.， 1967）. In the 1970s，ultra-fine powder tape casting began to appear. As the technology was advanced，many new products were successfully developed， and a number of tape castingapplications were grown. In 1996， capacitors with 5 ~tm film were successfullyfabricated by tape casting in Japan. By 1997， tape casting machinery， which couldform film of 5 ktm thickness， began to appear in Japan and the U.S.A. markets. In1998 it had been announced by researchers that the film with a thickness of 3 ktmhad been obtained through tape casting technology （Rechard E.， et al.， 1998）. Tape casting， as a processing method， is a multidisciplinary technique （RechardE.， et al.， 1998） which involves ceramic technology， powder surface physicalchemistry， gel chemistry， organic and polymer chemistry and so on. As tape-forming process had been put forward for several decades， and extensive studiesof the process were subjected to the attention of the scientific community， it hasundergone continuous improvement and enhancement.
Novel Colloidal Forming of Ceramics discusses several new near-net-shapetechniques for fabricating highly reliable， high-performance ceramic parts.These techniques combine injection molding and the colloidal formingprocess. The book not only introduces the basic theoretical developmentand applications of the colloidal injection molding of ceramics， but alsocovers tape casting technology， the reliability of the product， and thecolloidal injection molding of Si3N4 and SiC， as well as the low-toxicitysystem. The book is intended for researchers and graduates in materialsscience and engineering.Mr. Yong Huangand Dr. Jinlong Yang are both professors at the Departmentof Materials Science and Engineering， Tsinghua University， China.
