化学强化的二硅酸锂-透锂长石微晶玻璃的化学耐久性
Chemical Durability of Chemical Strengthened Lithium Disilicate-petalite Glass-ceramics
摘要
Abstract
Lithium disilicate-petalite glass-ceramic was prepared and chemically strengthened.The corrosion mechanism of glass in acid &alkaline conditions was studied by means of XRD and SEM.The experimental results show that the residual glass phase of lithium disilicate-petalite glass-ceramics is corroded first,and then the crystals are exposed.H+replaces Li in petalite,and the product HAlSi4O10 accumulates on the surface of the glass-ceramics.This experiment further explored the effect of glass formulation and the strengthening process on chemical durability.The results showed that reducing the content of Na2O in the base glass,increasing the content of ZrO2 and K2O,and adding a little LiNO3(0.03％)to the ion exchange salt bath could significantly improve the chemical durability of lithium disilicate-petalite glass-ceramics.关键词
