摘要

本发明有关于一种含固相反应之富金层银基导线制造方法，首先，准备含钙、钛或锆离子其中之一金属离子水溶液；再者，将奈米金粉加入水溶液内，奈米金粉于水溶液中形成复数颗金粒子，利用水热法将金属离子吸附于金粒子表面，以形成奈米核壳复合金粒子；之后，过滤水溶液以获得固相奈米核壳复合金粒子；接续，将固相奈米核壳复合金粒子置入银熔液，搅拌均匀以形成银基材，藉此，奈米核壳复合金粒子均匀分布于银基材；之后，进行二阶段真空热处理，使银基材表面形成富金合金层；最后，将银基材进行抽线制程以形成含固相反应之富金层银基导线。; adding nano gold powder into the aqueous solution to form a plurality of gold particles; using a hydrothermal method to absorb the metal ions on the surface of gold particles to form core-shell nano-gold composite particles; filtering the aqueous solution to obtain solid phase core-shell nano-gold composite particles; placing the solid phase core-shell nano-gold composite particles into silver solution and stirring them evenly to form a silver substrate, and thereby the core-shell nano-gold composite particles are distributed on the silver substrate uniformly; proceeding with a second stage vacuum heat treatment so that the surface of the silver substrate is formed into a gold-rich alloy layer; proceeding with a wire drawing process for the silver substrate to form a silver based wire containing a gold-rich layer formed by a solid phase reaction.
