Barium titanate (BaTiO3) is one of the well-known ferroelectric materials and has been studied by many researchers for use in multilayer capacitors, thermistors, and electro-optic devices. This material shows a permittivity maximum at around 130 °C, and the permittivity values change largely in the range of 0 - 120°C. For practical use in ceramic capacitors, higher permittivity with low temperature-dependence, particularly around room temperature (10 - 80°C), is required. To achieve this requirement, many kinds of dopants, such as Ca2+, Mg2+, or Zr4+, have been added to BaTiO3, which results in the suppression and/or broadening of the permittivity maximum and showing low temperature-dependence of permittivity. In addition to these doping methods, preparation of compositionally graded ceramics has also been attempted. For example, Ota et al. (2001) prepared (Ba1-xSrx)TiO3 laminated ceramics with varying x from one to the other side, and reported a flat permittivity profile (4000 - 5500) in the temperature range 30 - 110°C. Designing of this type of graded ceramics is based on the concept that the apparently observed permittivity is the summation of its respective value of the constituting component. Though the permittivity of the laminated ceramics is controllable by changing the volume fraction of the components, lamination of several components with different thermal expansion coefficient is rather difficult. Mixing the powders with several components, rather than laminating them, seems easy and simple from the manufacturing standpoint. However, there have been few techniques to prepare such ceramics consisting of compositionally graded grains, because the conventional sintering of mixed particles with different components usually results in the solid solution.
