Abstract
A ceramic material for an optical member which shows black, wherein the ceramic material comprises a reaction-sintered sintered ceramic body prepared by synthesizing a formed body of a mixture comprising a ceramic raw material and a component that accelerates blackening, making use of a reaction sintering; and wherein the ceramic material is a porous body.
Claims15
A ceramic material for an optical member which shows black,
- wherein the ceramic material comprises a reaction-sintered sintered ceramic body prepared by synthesizing a formed body of a mixture comprising a ceramic raw material and a component that accelerates blackening, making use of a reaction sintering;
- and
- wherein the ceramic material is a porous body.
A method for producing a ceramic material for an optical member which shows black, the method comprising:
- producing a body by forming a mixture prepared by adding a component capable of accelerating blackening to a ceramic raw material;
- and
- carrying out a reaction sintering by heating the obtained formed body, so as to prepare a reaction-sintered body.
