Abstract
PURPOSE: To prevent the copper powder from oxidation effectively, by covering the halogenated hydrocarbon compound on the surface of the copper powder used for an electroconductive paste.
CONSTITUTION: The oxidation of copper powder surface is prevented by covering halogenated hydrocarbon compound on the surface of the copper powder of an electroconductive paste used for forming the electrode, electroconductive circuit pattern on the ceramic substrate. For that, the halogenated hydrocarbon compound is covered by immersing in the solution of the halogenated hydrocarbon compound of Trichrene, Perchrene, Freon, chlorobenzene, acetone etc., or blasting the solution, or applying the solution, or evaporating. Then, the covering layer of the copper powder surface is protected by heat-treatment at 30W50°C.
