Abstract

Fourier transform infrared reflectance spectroscopy (FTIR-RS) was investigated as a potential tool for determining the volume fraction of crystals in partially-crystallized lithium disilicate (LS₂) glasses. The LS₂ glass samples were partially-crystallized at two temperatures, 583°C and 595°C, as a function of time. These temperatures were selected based on thermal analysis of LS₂ glass. The FTIR spectra of the polished sample surfaces were obtained in specular reflectance mode. The volume fraction of crystals in the samples was obtained via a point-count stereology technique. A relation between FTIR-RS peak intensities and the volume fraction of crystals in the partially-crystallized LS₂ glasses was then determined. This relation can provide a convenient quality control process for glass-ceramic industry.
