Crystallization of MgO–B2O3–SiO2 Slag Observed by In Situ TEM
-
Peixin Zhang
Abstract
Transmission electron microscopy (TEM) observation of in situ heated MgO–B2O3–SiO2 slag allowed the description of its dynamic crystallization process. The crystallization processes are constituted by two steps: (i) phase separation and (ii) nucleation and growth of 2MgO · B2O3 crystal precipitated prior to 3MgO · B2O3. The crystallization processes are sensitive to the electron beam. In electron irradiated regions, the phase separation occurred at 300 °C, however, the phase separation was observed in the electron non-irradiated region at about 750 °C.
