摘要

This article examines the thermochemical strengthening of aluminosilicate glass. The glass was treated in molten KNO3 under industrial and laboratory conditions at 440 – 480°C for 1 – 120 h. The influence of treatment parameters on the properties of the glass was evaluated using Vickers microhardness measurements and spectrophotometry. Compressive stresses were determined using magnetophotoelasticity. The depth of the compressed layer was assessed using local birefringence analysis, and cation exchange was monitored by x-ray fluorescence analysis. A relationship was established between the temperature–time parameters of ion exchange and variations in the structural, mechanical, and optical properties of the glass.
