IR, DTA and XRD Study of MgO-Al_2O_3-SiO_2 Glass-Ceramic
Source abstract
Abstract
The processes of the phase-separation, nucleation and crystallization of the MgO- Al2O3-SiO2 glass containing TiO2 and ZrO2 were studied by the methods of infrared spectra, differential thermal analysis, X-ray powder diffraction, and electric microscopy. Phase-separation was found first during the heat treatment of the glass. The phase like drops contained more Ti element and surrounded by other phases. The analogous structure was remained during the nucleation process. Titanium ions were found to be of six-coordination, which accounted for the crystallization of the crystals containing titanium element.
