The Formation of a New Phase during Crystallization of TiO2-Doped Nd2O3-Al2O3-SiO2 Glasses
Glasses with the general compositions xNd 2O3.20Al2O3.(80–x)SiO2 and 15Nd2O3.yAl2O3.(85–y)SiO2 (x = 10, 15, 20, and y = 20, 25, 30) were prepared by melting at 1550°C. The glasses also contained varying amounts of TiO2 as nucleating agent. The microstructural evolution of the undoped and TiO2-containing glass-ceramics was then studied. Crystallization of the glasses was feasible in the range 1000° to 1250°C. The crystallization rates were evaluated. TiO2 addition influenced only the growth rate and not the nucleation of the crystalline phases observed in this study. Glasses of higher SiO2 content showed a rise in growth rate. It was found that when TiO2 was present, a new unreported crystalline compound with the stoichiometric composition of TiO2.Nd2O3.Al2O3.2SiO2 was formed GRAPHICAL ABSTRACT
期刊介绍:
