Abstract
Two dimensional images of the distribution of the relative values of the temperature coefficient of the dielectric constant of a two phase composite ceramic composed of TiO2 and Bi2Ti4O11 are observed using a photothermal dielectric microscope. The images clearly show that each grain of TiO2 has a negative temperature coefficient and each of Bi2Ti4O11 a positive one, and that the macroscopic averaged temperature coefficient of the ceramic is relatively small due to the cancellation of the coefficients with opposite signs.
