Dielectric Studies of Tin Oxide and Tin Dioxide Added with Barium Titanate

Abstract

In the present work, tin oxide (SnO) and tin dioxide (SnO₂) are added to barium titanate in various weight percentages (0%, 2%, 4%, and 6%) and sintered at 800° C for 4 h. The primary peak angle shifts to the lower angle, indicating changes in unit cell structure. The dielectric constant reduces initially for 2% SnO and SnO₂, but then increases, showing that tin accumulates in oxides form, resulting in an increase in polarization. The dielectric constant of SnO₂ is found to be greater than that of SnO, illustrating the role of the oxygen ion.
