Alumina (Al 2 O 3) can be considered as an intermediate, because it can be both a glass former and a glass modifier in binary oxide glasses, although Al 2 O 3 cannot solely form glass.Web
The results showed that the chemical composition significantly influences the crystallization of the CaO-SiO2-Al2O3 glass. Decreasing basicity (R = 0.8–1.2, the mass ratio of CaO and SiO2) favors the crystallization of the glass phase, while increasing the content of Al2O3 (9–12%) can inhibit the crystallization of the glass phase.Web
