Conductive Silver-Coated Monodisperse Silica Microspheres 2.3g/cc to 4.1g/cc, CV<10% - 2um to 9um

Product Line: SiO2MS-AG

Conductive monodisperse silica microspheres are made from a solid silica interior coated with a thin layer of silver (Ag) metal. This strategic combination of materials offers 1) the unique electrical conductivity and reflectivity of silver metal coating and 2) the narrow particle size distribution and spherical shape of monodisperse slica microspheres (CV<10%). These high precision silver-coated silica microspheres offer a conductive spacer option for LCD displays and other electrical components.

SiO2MS-AG-4.1 2.0um - 200mg -- Coated with ~85nm of silver
SiO2MS-AG-3.5 4.5um - 500mg -- Coated with ~110nm of silver
SiO2MS-AG-2.3 9.0um – 500mg -- Coated with ~75nm silver

We also offer uncoated option of Monodisperse Silica Microspheres and Polydisperse Silica Microspheres as well as Conductive Silver Coated Polymer Spheres and Conductive Silver Coated Glass Spheres.

Questions:
Hi! I had a couple questions about these microspheres. Is it possible to make a custom coating such that the final particles are still optically transparent at 1064nm? We use non-coated silica spheres in an optical trap for physics experiments, and we may benefit greatly from a thin metallic coating. Also, how are the microspheres delivered? Are they in suspension or as a dried powder? Thanks!
Answers:
Our silver-coated microspheres are delivered as dry powder. In regards to a custom transparent conductive coating, this may be possible, however, it would require a custom order with a minimum order quantity and associated leadtime.
