There are two representative forming methods for ceramics such as pressure forming, which gives dynamic pressure to raw materials directly, and slip casting using capillalry attraction. In addition, there is an electrophoretic forming(electrophoretic and electroosmotic forming), which has been discussed as the third forming method, making use of surface charge of raw materials. Electrophoretic phenomena is explicated theoretically in an dilute system and there are many applications. However, it has a lot of unsolved problems in a concentrated system and its application is limited. And there are few industrial applications aiming at forming.In this paper, the fundamentals and the control factors of the electrophoretic (electroosmotic) forming, using natural inorganic materials as a starting material will be discussed. In addition, using these theory, continuous forming technology will also be discussed.
