MANUFACTURING METHOD OF ALUMINA SINTERED BODY AND ALUMINA SINTERED BODY
To provide a manufacturing method of an alumina sintered body that includes a transparent alumina sintered portion usable as a transparent member, and the alumina sintered body obtained from the manufacturing method.SOLUTION: A manufacturing method of an alumina sintered body includes the steps of: molding an alumina powder containing alumina particles with a particle diameter of 0.1 μm or more and less than 1 μm and alumina particles with a particle diameter 1 μm or more and less than 100 μm to obtain an alumina article; forming a carbon powder-containing layer on a surface of the alumina article to obtain a laminate body; and irradiating the surface of the carbon powder-containing layer of the laminate body with laser to form a transparent alumina sintered portion.SELECTED DRAWING: Figure 4
【課題】透明部材として使用可能な透明アルミナ焼結部を含むアルミナ焼結体の製造方法、およびその製造方法で得られたアルミナ焼結体を提供することを目的とする。【解決手段】粒径０．１μｍ以上１μｍ未満のアルミナ粒子と、粒径１μｍ以上１００μｍ未満のアルミナ粒子と、を含むアルミナ粉末を成形して、アルミナ物品を得る工程と、前記アルミナ物品の表面に炭素粉末含有層を形成して積層物を得る工程と、前記積層物の前記炭素粉末含有層の表面にレーザを照射して、透明なアルミナ焼結部を形成する工程と、を含むアルミナ焼結体の製造方法。【選択図】図４
