Application: Flake silver powder is a high-performance conductive filling material with good oxidation resistance. Flake silver powder is the main raw material for making conductive coatings, film switches, conductive inks, conductive rubber, conductive plastics, conductive ceramics, etc.
Flake silver powder is very good Low temperature polymer slurryIdeal raw materials for conductive coatings, conductive paints, and electromagnetic shielding coatings. The coating prepared with flake silver powder has good fluidity, anti settling, and a large spraying area.
2) Spherical silver powder:
Common particle size:< 1um, 1-3um, 3-5um, 5-8um, 10um, particle size and parameters can be customized according to requirements.
Application: Near spherical silver powder is mainly suitable as a conductive filler for high-temperature sintered silver paste.
There is no absolute standard for the superiority or inferiority of silver powder as a conductive filler. The selection of silver powder should be based on the corresponding binder, the public welfare of the target conductor material, the physical and chemical properties of the film layer, and the requirements for reliability.
2. Silver copper conductive powder (commonly with particle sizes of 1-3um, 3-5um, 5-8um, 10um, and Ag content ranging from 3% to 35%)
characteristic:
1) Silver coated copper powder has a small particle size, which can reach the sub micron level.
