ELECTRICALLY CONDUCTIVE POWDER, PRODUCTION METHOD THEREFOR, AND ELECTRICALLY CONDUCTIVE PASTE OBTAINED BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide electrically conductive powder which has excellent crystallinity, dispersibility and oxidation resistance, and is used for thick film electrically conductive paste, e.g., for forming the internal electrode of a multilayer ceramic capacitor, to provide a production method therefor, and to provide electrically conductive paste obtained by using the same. SOLUTION: The production method for electrically conductive powder comprises: a stage (A) where a dispersion solution of metal powder is added and mixed with boron oxide or boric acid of 40 to 100pts.wt. expressed in terms of B2O3to 100pts.wt. of the metal powder, and thereafter, the dispersion solution is dried to obtain a mixture consisting of the metal powder and boron oxide or boric acid; a stage (B) where the mixture is subjected to heating treatment in a neutral atmosphere to obtain a heat-treated product; and a stage (C) where the heat-treated product is subjected to dissolution treatment with water or acid to obtain metal powder.
