  • Patent number: 5102483
    Abstract: A method for production of a ceramic sheet includes the following steps: First, a pair of green sheets are prepared from ceramic material by the doctor-blade method. Each of the green sheets has first and second surfaces. The prepared sheets are placed one on the other and adhered to each other in such a manner that the first surfaces of the green sheets oppose each other. Alternatively, the second surfaces of the sheets may oppose each other. As a result, a united green sheet is obtained. A separating sheet is disposed on a side of the united green sheet. The united green sheet is rolled, with the separating sheet, around a core. The united green sheet, with the separating sheet, is sintered in a rolled configuration thereby producing a rolled ceramic sheet.
