Ceramic material and method for manufacturing ceramic product utilizing it |
摘要 |
<p>A ceramic material is a calcined article obtained by calcining a molded ceramic article and in which the pores of the calcined article are impregnated with a substance which can be removed at a temperature lower than a sintering temperature for the molded ceramic article. A method for manufacturing a ceramic product includes the steps of calcining a molded ceramic article, impregnating the open pores of the calcined ceramic article with a substance which can be removed at a temperature lower than a sintering temperature for the calcined ceramic article, mechanically machining the ceramic article to impart a desired shape thereto, removing the substance from the ceramic article, and then sintering the ceramic article. Large-sized ceramic products having a high strength and an excellent shape accuracy and having complex shapes can be manufactured at low costs. The change of the product shape can be accomplished only by changing a program for operation, and for the ceramic products having various shapes, a prompt design changing is possible.</p> |
