More Information
Summary:To provide a method for producing a ceramic plate capable of reducing electrical insulation.SOLUTION: A method for manufacturing a ceramic plate comprises an irradiation step in which the main surface of a plate-like ceramic sintered body is irradiated with ultraviolet light from a UV light source to transform at least a part of the ceramic sintered body. In the irradiation step, the integrated light intensity of the UV light with a wavelength of 10-450 nm applied to the main surface of the ceramic sintered body is 1000 mJ/cm2 or more.SELECTED DRAWING: Figure 1 【課題】電気絶縁性を低減することが可能なセラミック板の製造方法を提供すること。【解決手段】板状のセラミック焼結体の主面にＵＶ光源からの紫外線を照射し、セラミック焼結体の少なくとも一部を変質する照射工程を有する、セラミック板の製造方法を提供する。照射工程において、セラミック焼結体の主面に照射される波長１０～４５０ｎｍの紫外線の積算光量は１０００ｍＪ／ｃｍ２以上である。【選択図】図１
