Effect of microwaves on the migration of lithium and silicon from lithium disilicate (Li2O-2SiO2) glass.
Lithium disilicate (Li2O-2SiO2) glass was immersed in a static solution of deionized water and heated by a microwave or by conventional means for various times. The resulting Li+ and Si migration was compared by solution analysis and the corroded glass surfaces were compared by Fourier transform infrared reflection spectroscopy and scanning electron microscopy. Results show no substantial differences in migration or glass corrosion under the test conditions using 7.00 GHz microwave radiation, but leave open the possibility of very slightly altered kinetics using 5.86 GHz radiation. More testing at 2.45 GHz is suggested.
