Modulation of Lithium Disilicate Translucency through Heat Treatment [PDF]
Materials, 2021 The aim of this study was to present a control method for modulating the translucency of lithium disilicate ceramics through thermal refinement. Identical lithium disilicate blocks were thermally refined using four different heat treatment schedules, and the microstructure, translucency, and flexural strength of the ceramics were investigated in detail

The effects of ultrasonic cavitation on the dissolution of lithium disilicate glass
Scientific Reports, 2022 AbstractThere has been little research conducted on how ultrasonic cavitation may affect glass dissolution. The focus of this study was to examine how the mechanisms and kinetics of glass dissolution may change in a system that included ultrasonication. Experiments were conducted on lithium disilicate glass in deionized water at 50 °C between 1 and 7.5
