A glass with the eutectic composition 3MnO 1.5 –2SiO 2 was used to simulate the formation of a liquid phase during sintering of BaTiO 3 . Two oxide additives (Mn 2 O 3 and SiO 2 ) performing various functions of the properties of BaTiO 3 were investigated for their crystallization and thermal characteristics at temperatures ≤1400°C. The wetting behavior of the glass, the dissolution of BaTiO 3 in glass melt, the identification of newly formed phases, and the sequential reaction kinetics of the glass/BaTiO 3 system, especially when isothermally treated at 1150°C, were investigated by electron microscopy with quantitative X‐ray energy dispersive spectroscopic (Q‐EDS) analysis. The evolution of the interfacial reaction of the glass/BaTiO 3 at 1150°C is reported and discussed.
