M.Hillers, G.Matzen, E.Véron, M.Dutreilh-Colas, A.Douy, 'The Application of In-Situ High Temperature Techniques to Investigate the Effect of B2O3 on the Crystallization Behavior of Aluminosilicate E-Glass', J. Am. Ceram. Soc. 90 720-726 (2007) doi:10.1111/j.1551-2916.2006.01469.x

Using classical ex situ techniques (optical microscopy, Raman spectroscopy), differential scanning calorimetry, and two new in situ techniques for characterization during crystallization (high-temperature environmental scanning electron microscopy and high-temperature X-ray diffraction with a fast detector), the addition of B2O3 to SiO2–Al2O3–CaO glasses was examined to understand its impact on crystallization behavior. The conventional ex situ characterization reveals that B2O3 addition reduces crystal growth rate and also decreases the liquidus temperature. The in situ techniques provide complementary information on the crystallization kinetics.
