The ideal characteristics of silver coated copper powder largely depend on the perfection and consistency of the silver coating at the microscopic level. High quality silver coated copper powder is a prerequisite for realizing its application value. The core goal and difficulty of the preparation process is to achieve uniform, dense, continuous, and thickness controllable silver layer coverage on ...

First、 Physical Law Physical methods can usually prepare copper powder with high purity and good sphericity. 1.Atomization method Aerosolization method: using high-pressure inert gas, the resulting powder has low oxygen content and good sphericity, but the cost is relatively high. Commonly used in high-performance powder metallurgy and 3D printing of metal powders. Water atomization method: using ...

Behind the flourishing development of many industries such as electronics and new energy, there is a seemingly insignificant but crucial material - conductive silver paste. Keyboards, mobile phones, tablets, solar panels, smart cards, RFID and other devices rely on them to achieve connections and fully function. Silver has the highest conductivity among metals, with excellent conductivity, thermal...

The meanings of metamorphic treatment, grain refinement, and primary phase refinement or morphology change are different, and sometimes the term metamorphic treatment is used to summarize these contents. (1) Deterioration treatment. For simple binary Al Si alloys, such as Z102 containing 11%~13% Si, it is a typical eutectic alloy. Its organization consists of coarse needle shaped (should be layere...
