Abstract
WO 200232823 A UPAB: 20060227 NOVELTY - Thermally tempered safety glass has a porous silicon dioxide layer having a refractive index of 1.25-1.40. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a process for the production of the safety glass comprising coating a standard soda-lime glass with an aqueous coating solution having a pH of 3-8 and containing 0.5-5.0 wt.% (SiOx(OH)y)n particles (where y = 0-4; and x = 0-2) having a particle size of 10-60 nm; drying the coated glass by leaving to stand at room temperature or by drying in an air stream; hardening the glass at at least 600 deg. C for 2-10 minutes; and thermally tempering using a flow of air. USE - Used for covers of solar collectors, for photovoltaic cells, for vehicle windscreens and/or for glazing (claimed). ADVANTAGE - The glass has high stability.
