| description | PURPOSE:To manufacture a ceramic sheet superior in surface smoothness, by a method wherein a multi-layer green sheet comprised of ceramic powder whose mean particle diameter is smaller than that of an intermediate layer is baked on both surfaces of the intermediate layer comprised of the ceramic powder whose mean particle diameter is 0.8-0.3mum. CONSTITUTION:A multi-layer green sheet is formed of an intermediate layer and a top and bottom layers for which ceramic powder whose mean diameter is 0.8-3.0mum and ceramic particles whose mean particle diameter is smaller than that of the intermediate layer are used respectively. Slurry for the top and bottom cast in thickness of about 0.1mm by a molding machine for which a doctor plate is used is dried and then slurry for the intermediate layer is cast to the top in thickness of about 0.8mm for drying, in formation of the green sheet. A ceramic sheet obtained through baking is scarcely warped and superior in surface smoothness. |
