Curie Temperature of BaTiO3

The Curie point (T
C) of BaTiO3 was earlier reported to be 120° C and has been recently believed to be 130° C. Some experiments have been performed here to reconfirm the T
C. Firing conditions used for preparing BaTiO3 were examined first with the use of pure BaCO3 or Ba(NO3)2 and TiO2. The x-dependence of T
