Abstract:We have developed a strengthening coating based on silica nanoparticles for soda-lime-silica glass, examined conditions for the synthesis of SiO2 particles with tailored structure and application of coating of necessary thickness to glass through adsorption from solution, and optimized heat treatment of the coated glass. The nanohardness and centrosymmetric bending strength of the coated glass have been measured, and the mechanism behind the coating-induced increase in glass strength is discussed.
