Al2O3-TiO2-SiO2Phase relations in the Al2O3–TiO2–SiO2 system have been investigated experimentally using X-ray diffraction, scanning electron microscopy combined with energy-dispersive X-ray spectrometry, and differential thermal analysis. The solid-state invariant reaction SiO2+Al2TiO5Al6Si2O13+...
