Abstract
Official abstract text for this publication.
A method for manufacturing a ceramic member includes a mark process for forming a mark indicating information about a ceramic green body on the ceramic green body by using a mark material capable of being erased by a predetermined heat treatment; and a heat treatment process for erasing the mark by applying the ceramic green body to the predetermined heat treatment.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing a ceramic member comprising: a first mark process for forming a first mark indicating information about a ceramic green body on the ceramic green body by using a first mark material capable of being erased by a predetermined heat treatment; a second mark process for forming a second mark indicating information about the ceramic green body on the ceramic green body by using a second mark material not capable of being erased by the predetermined heat treatment, the second mark material being different from the first mark material; and a heat treatment process for erasing the first mark and not erasing the second mark by applying the ceramic green body to the predetermined heat treatment. 2. The method for manufacturing a ceramic member according to claim 1 , wherein the information shown by the first mark is at least one of unique identification code, quality, inspection result, manufacturing condition, front and back orientation, and positioning mark of the ceramic green body, and the information shown by the second mark is at least one of unique identification code, quality, inspection result, manufacturing condition, front and back orientation, and positioning mark of the ceramic green body. 3. The method for producing a ceramic member according to claim 1 , wherein the predetermined heat treatment is a firing treatment at 500 degrees C. or higher.
