摘要：Chemical strengthening of aluminosilicate glasses through K+-Na+ ion exchange has attracted tremendous attentions because of the accelerating demand for high strength and damage resistance glasses. However, a paramount challenge still exists to fabricate glasses with a higher strength and greater depth of ion-exchange layer (DOL). Herein, aluminosilicate glasses with different contents of P2O5 were prepared, and the influence of P2O5 on the increased compressive stress (CS) and DOL was investigated by micro-Raman technique. It was noticed that the hardness, CS, as well as the DOL substantially increased with an increasing concentration of P2O5 varied from 1 to 7 mol%. The obtained micro-Raman spectra confirmed the formation of relatively depolymerized silicate anions that accelerated the ion exchange. Phosphorus-containing aluminosilicate glasses with a lower polymerization degree exhibited a higher strength and deeper DOL, which suggests that the phosphorus-containing aluminosilicate glasses have promising applications in flat panel displays, windshields, and wafer sealing substrates.
