Preparation of ceramic tube by electrophoretic deposition processing

摘要

The present invention relates to a method for manufacturing a ceramic tube, comprising placing a ceramic suspension in a metal container and immersing a negative electrode rod made of a material having conductivity and flammability and / or peelability while immersing the negative electrode in a metal container. Coating a ceramic to the negative electrode by applying a positive voltage, and removing the negative electrode coated with the ceramic, and then removing the negative electrode by burning and / or peeling to obtain a ceramic tube. According to the present invention, it is possible to manufacture a high precision ceramic tube with a simple production process, high production speed, and low production cost, and the ceramic tube thus manufactured is very useful as a material for piezoelectric materials and superconductor.
