CONDUCTIVE COMPOSITION, METALLIZED SUBSTRATE, AND METHODS FOR PRODUCING THE SAME
To provide a conductive composition capable of forming a conductive part having high adhesion to a ceramic substrate.SOLUTION: The conductive composition is prepared by combining: metal particles (A) comprising isotropic Ag particles (A1) having a median particle diameter of 1-7.5 μm and composite particles (A2) of Ag and Pd; glass particles (B); and a metal component (C) comprising an Mn component (C1), an Fe component (C2) and a Cu component (C3). The ratio of Pd to the total amount of Ag and Pd in the composition is about 0.5-5 mass%. The Ag particles (A1) may be spherical particles having a median particle diameter of 1.5-2.5 μm. The glass particles (B) may include borosilicate glass particles and/or zinc-based glass particles.SELECTED DRAWING: None
