 摘要
 
 银铜焊料是Ag-Cu二元合金的共晶组织成分，其熔点适中，工艺性好，并具有良好的强度、韧性、导电性、导热性和抗腐蚀性，在电真空开关、断路器、陶瓷焊接等方面都极具应用性。
 本文对低含氧量银铜焊料的润湿性及溅散性进行了分析，并对制粉工艺进行探讨，并通过其在陶瓷工业上的应用，对其性能进行了详细分析。

关键词：银铜焊料 润湿性 溅散性 陶瓷 制粉工艺

Abstract

 Ag-Cu filler is a binary alloy Ag-Cu eutectic composition. Silver-based filler has medium melting point, with good technology, good strength, toughness, electrical conductivity, thermal conductivity and corrosion resistance. Especially for the highly application in the power vacuum switcs, circuit breakers, ceramic welding,ect.
 This passage puts forward the impact of oxygen levels in Ag-Cu filler on wettability and sputter of filler, and explore to Manufacture of powder technology，through its application in the ceramic industry，We get the detailed performance analysis. 

 Key Words: Silver-based Filler；Wettability；Sputter；Ceramics ；Manufacture of Powder Technology
