Abstract
A manufacturing method for a sintered body having a metallic member buried therein is provided, and includes forming an alumina sintered body, forming a metallic member by printing a printing paste including a refractory metal on the alumina sintered body, forming a green alumina compact on the metallic member, and sintering the alumina compact, the metallic member, and the alumina sintered body or the alumina presintered body.
Claims9
A manufacturing method for a sintered body having a metallic member buried therein, comprising:
- forming an alumina sintered body having a first surface and an opposed second surface;
- polishing the opposed second surface of the alumina sintered body;
- forming a metallic member by printing a printing paste including a refractory metal on the polished second surface of the alumina sintered body;
- forming a green alumina compact on the metallic member;
- hot pressing the green alumina compact, the metallic member, and the alumina sintered body to sinter the green alumina compact, the metallic member and the alumina sintered body together to form a sintered body having the metallic member buried therein;
- and
- grinding the first surface of the alumina sintered body to adjust a thickness thereof, thereby forming a substrate-placing surface of the sintered body.
