Abstract
A method of fabricating a sintered ceramic composite body having at last one hollow portion therein is disclosed. According to this method, at least one green ceramic body in the form of a sheet or plate and an adhesive sheet made of a ceramic powder and a binder resin are provided. The adhesive sheet is capable of adhering to the green ceramic body after drying and is shaped to provide a hollow portion in association with green ceramic body. The adhesion body and the green ceramic body are brought into intimate contact with each other so that a hollow portion is established therebetween. The resulting composite body is pressed and sintered to obtain a sintered ceramic composite body having the hollow portion therein. The binder preferably includes acrylic resin(s) and/or vinyl resin(s) having a molecular weight of 300,000 to 800,000 and a glass transition temperature of -30.degree. C. or below.
