Active metal soldering paste composition, soldering paste and method for welding ceramic and metal
The invention relates to an active metal soldering paste composition, soldering paste and a method for welding ceramic and metal. The composition comprises a binder and metal powder. The metal powder comprises active metal welding powder and weld-aid metal powder; the weld-aid metal powder comprises copper powder and/or copper-silver alloy powder; the active metal welding powder is alloy powder of copper, silver and active metal; based on the total weight of the metal powder, the content of the active metal is 1.5% by weight or more, the content of silver is 40-90% by weight, and the content of oxygen is 0.5% by weight or less. The active soldering paste composition is high in welding activity, and the welding quality and the bonding strength can be improved when the active soldering paste composition is used for welding metal and ceramic; and meanwhile, the material cost of the soldering paste can be reduced.
本发明涉及一种活性金属焊膏组合物、焊膏及焊接陶瓷与金属的方法，该组合物包括粘结剂和金属粉末；所述金属粉末包括活性金属焊粉和助焊金属粉末；所述助焊金属粉末包含铜粉和/或铜银合金粉；所述活性金属焊粉为铜、银和活性金属的合金粉末；以所述金属粉末总重量为基准，所述活性金属的含量为1.5重量％以上，银的含量为40～90重量％，氧的含量为0.5重量％以下。本公开的活性焊膏组合物的焊接活性高，采用该焊膏组合物对金属和陶瓷进行焊接能提高焊接质量和结合强度；同时，能够降低焊膏的材料成本。
