Evolution of interfacial microstructure between BaTiO 3 and the binary glasses used as frits in thick‐film technology has been studied. Possible reaction mechanisms for the interfacial compounds have been determined by comparing the results of the sintering study with the reaction of BaTiO 3 , powder with glass powders. The interfacial microstructure can be divided into two types. The first type of interfacial microstructure is observed for glasses rich in PbO or Bi 2 O 3 network modifiers and is characterized by the penetration of glass into the BaTiO 3 grain boundaries, accompanied by incorporation of Pb into the perovskite lattice. The second type of interfacial microstructure is observed for glasses rich in B 2 O 3 or SiO 2 network formers and is characterized by the formation of interfacial compounds.
