積層構造体及びその形成方法
Document Type and Number:
Japanese Patent JP4845315
Kind Code:
B2
Abstract:
A method of alleviating edge curling when laminated structures comprising layers of green material having different shrinkage rates are sintered comprises applying to a face ( 18 ) of edges ( 14 ) the first layer ( 10 ) having the higher shrinkage rate green sinterable material, opposite to the second layer ( 12 ) having the lower shrinkage rate green sinterable material, an edge strip ( 16 ) of a green sinterable material also having a shrinkage rate lower than the first layer, and then firing the laminated structure. The edge strip may be partly or, advantageously, wholly embedded in the first layer. The sinterable materials of the second layer and edge strip may be the same or similar. The invention is particularly applicable to solid oxide fuel cell sub-structures in which the first layer is the anode layer and the second layer is the electrolyte layer.
