Abstract
A light-scattering coating comprising light-scattering particles, such as alumina, dispersed in a silica matrix is formed by applying to the filter a silicone solution in which is dispersed colloidal silica and the light-scattering particles to a suitable substrate and then pyrolyzing the dispersion at high temperature to drive off the organic components and form the silica matrix. This coating is hard and abrasion resistant and is useful for reflectors, lamps and lenses.
