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.
