Core-shell structure conductive microsphere with adjustable specific gravity as well as preparation method and application of core-shell structure conductive microsphere
The invention discloses a core-shell structure conductive microsphere with adjustable specific gravity as well as a preparation method and application of the core-shell structure conductive microsphere. The conductive microsphere comprises a ceramic microsphere serving as a core and a metal shell layer coating the surface of the ceramic microsphere. The ceramic microsphere and metallized paste are used as raw materials, and the surface of the ceramic microsphere is coated with the metal shell layer with a certain thickness through a solid-phase sintering method. By adopting the metallization method disclosed by the invention, the bonding strength of the obtained metal shell layer and the surface of the ceramic microsphere core is high, the core-shell structure is compact, the metal shell layer is not easy to fall off, and the diameter of the obtained conductive microsphere with the core-shell structure is adjustable between 1-2000 [mu]m; meanwhile, the overall specific gravity of the core-shell structure microsphere can be adjusted by adjusting the diameter of the ceramic microsphere and the thickness of the coating metal shell layer, so that the conductive microsphere with different use requirements can be obtained; and further electroplating treatment can be carried out on the metal shell layer to improve the conductivity and smoothness of the metal shell layer, so that the application field of the conductive microsphere is widened.
