ABSTRACT:
A method of connecting a metal (1) with a ceramic material (2) comprises the steps of providing a through-hole (3) in the ceramic material and positioning the metal (1) to be connected to the ceramic material (2) proximate to the ceramic material (2) with the through-hole (3). Subsequently, the metal (1) is melted (7) proximate to the through-hole (3). A pressure difference prevails between the side of the ceramic (2) remote from the metal and the side of the metal (1) remote from the ceramic material (2). A larger pressure prevails at the side of the metal (1) remote from the ceramic material (2). The pressure difference causes the melt (7) to be pressed into the through-hole (3) in the ceramic material (2). The through-hole (3) has such a shape that, after solidification, the solidified material (14) and the through-hole (3) have a complementary locking form.
