Multi-layer composite ceramic plate and manufacturing method thereof
Disclosed are a multi-layer composite ceramic plate and a manufacturing method thereof. The composite ceramic plate includes at least one basic sandwich structure. The manufacturing method includes: preparing a sheet-like green body with ceramic powders; pre-sintering the green body at a pre-sintering temperature lower than the sintering temperature to obtain a pre-sintered ceramic member with certain strength; forming a metal electrode layer on an upper surface of the pre-sintered ceramic member; placing the pre-sintered ceramic member in a mold, with the upper surface coated with the metal electrode layer facing upwards; providing a ceramic precursor layer on the upper surface of the pre-sintered ceramic member; carrying out hot-pressing sintering in the axial direction of the pre-sintered ceramic member at the sintering temperature to form an integral structure, wherein by the hot-pressing sintering, a second ceramic layer is formed by the pre-sintered ceramic member, a first ceramic layer is formed by the ceramic precursor layer, and the metal electrode layer is located between the first ceramic layer and the second ceramic layer to from a basic sandwich structure together with the first ceramic layer and the second ceramic layer.
