Title: Manufacture of ceramic structure
Inventor: UCHIMURA KATSUJI
IPC: B28B1/38
Filed: 1987-11-13
Abstract: PURPOSE:To make it possible to form highly accurate and small holes without using mold and consequently realize low production cost by a method wherein electrically conductive paste is printed onto an insulating sheet member and, after that, the required thickness of ceramic is deposited onto the paste by electrophoresis and finally the ceramic is fired. CONSTITUTION:Electrically conductive paste P is printed in the shape of a vertically extending lattice by a printing roller 2 on the surface of a sheet member 1. The printed sheet member 1 is immersed in slurry-like ceramic by being shifted in a vessel 5, which contains the slurry-like ceramic. When the sheet member 1 is immersed in the slurry-like ceramic for one minute, a nearly 3mm thick aluminum oxide of the slurry-like ceramic deposits on the portion printed with the electrically conductive paste P. Next, the sheet member 1 is pulled up from the vessel 5, cut off in proper size and, after that, ceramic is forcibly dried and finally fired at 1600 deg.C in an electric oven. As a result, the sheet member 1 and the electrically conductive paste 1 are burnt away, resulting in obtaining a ceramic structure consisting of lattice-like plate.
