Where is silver in spherical shape used other than for solar cell electrodes? Most of the silver in electronics seems to be flake. Is this statement accurate?
Dear Dan Colomb please find attached an article describing the preparation of spherical silver nanoparticles. Various other articles reporting the preparation and uses of spherical silver particles are available on RG, e.g.
Article Multifunctional properties of spherical silver nanoparticles...
Article The formation of monodisperse spherical silver particles
Article Spherical silver nanoparticles in the detection of thermally...
