US 7,390,449 B2 · Method of manufacturing ceramic material body

Abstract

A method of manufacturing ceramic bodies comprising the steps of: preparing a ceramic sheet; forming through holes in the ceramic sheet, each of the through hole forming at least one part of the contour of each ceramic bodies; and cutting the ceramic sheet into pieces of ceramic bodies. The ceramic sheet can be a single ceramic sheet or a laminate of ceramic sheets. The method of manufacturing ceramic bodies further comprises a step of forming a recess in the ceramic sheet, or pressure molding or partially removing of the ceramic body, as required. The manufacturing method provides inexpensive production of small ceramic elements having a complicated shape and extremely smooth surfaces with less uneven filling and nonuniform density.

Dependent claims

A method of manufacturing a ceramic body by a sheet forming process comprising:

providing a ceramic sheet;
forming at least two parallel channels in said ceramic sheet, said parallel channels having three sides, said parallel channels being at least one part of a contour of a ceramic body and wherein a thickness of said ceramic sheet at portions where said at least two parallel channels are formed is thinner than other portions of said ceramic sheet;
forming a through hole in said ceramic sheet, said through hole being connected to one of said parallel channels, and at least one surface of said through hole comprising a flat surface of the contour of the ceramic body;
and
cutting said ceramic sheet to form a ceramic body,
wherein at least part of the contour of said ceramic body comprises a combination of a flat surface and a slanted surface intersecting the flat surface at an angle, said slanted surface being at least one surface of said parallel channels.
