By Coating

Coated microspheres offer numerous advantages to scientists, engineers, and researchers, due to the combined properties of the core substrate material (e.g. solid or hollow glass, or polymer) and the functional coating (e.g. metal, silane, or fluorocoatings). The number of possible combinations is huge.

For example, applying a thin gold coating to solid barium titanate glass microspheres produces slightly conductive high density glass microspheres. (Density: ~4.49g/cc).

Solid barium titanate glass microspheres hemispherically coated with a thin aluminum coating offer retroreflective properties. Hemispherical aluminum coating and the high refractive index of the solid glass barium titanate spheres are both critical in achieving retroreflectivity. The light passes through the clear half of the microspheres and bounces off the aluminum coating.

"Conductospheres" or nickel-coated hollow microspheres offer a unique combination of a lightweight conductive spherical powder, which can be used to provide electrical conductivity as a lightweight filler in paints, adhesives, and composites.

Conductive silver-coated poly(methylmethacrylate) PMMA microspheresConductive silver-coated poly(methylmethacrylate) PMMA microspheres are ideal where some deflection is required while maintaining conductivity.

Many choices of coated microspheres are available, including custom partial coatings on glass microspheres and many metal-coated microparticles. If you don't see what you are looking for, please contact a microparticles expert for a recommendation.
