Material Safety Data Sheet - Amorphous Silica Microspheres and Nanospheres

Monodisperse silica microspheres and nanospheres are ceramic spherical beads with tight particle size distributions and CV<10%. Offered as a dry powder, these precision spherical micro and nanoparticles are chemically-stable, inert, safe materials, frequently used as fillers and spacers for biotechnology, sintering, microfluidics, electronics, optical coatings, medical devices and other high tech applications. Untreated silica spheres are typically hydrophilic and negatively charged. However, these parameters are not fixed, and might vary depending on the properties system the spheres are incorporated into.

Silica spheres are manufactured using proprietary technologies which allow the essential properties of amorphous silica to be maintained while simultaneously achieving controlled spherical shape and uniform particle size.
