A medical device and a method and process for at least partially forming a medical device, which medical device has improved physical properties.

What is disclosed is an electrode material including a sintered body containing a heat resistant element and Cr and being infiltrated with a highly conductive material. A powder mixture of a heat resistant element powder and a Cr powder is subjected to a provisional sintering in advance, thereby causing solid phase diffusion of the heat resistant element and Cr. After a Mo—Cr solid solution obtained by the provisional sintering is pulverized, the pulverized Mo—Cr solid solution powder is molded and sintered. A sintered body obtained by sintering is subjected to a HIP treatment. The highly conductive metal is disposed on the sintered body after the HIP treatment, and infiltrated into the sintered body by heating at a predetermined temperature. By conducting the HIP treatment, the withstand voltage capability and current-interrupting capability of the electrode material are improved.
