Succeeding to 60(Ba,Sr)TiO(3)-10A1(2)O(3)-30SiO(2)glassceramics reported in our previous paper, another type of ferroelectric glass-ceramics was elaborated by the controlled growth of Ba(l-x)Ca(x)TiO(3) crystal particles in the glass system 60 (Ba(l-y)Ca(y)) TiO(3)-10Al(2)O(3)-30SiO(2) (0.0<y<0.25) in molar basis. Analysis of crystal phases by X-ray diffraction revealed that Ca content in the crystal phase of Ba(l-x)Ca(x)TiO(3) increased with increasing amount of CaO in glass up to y=0.125, and the composition of Ba(l-x)Ca(x)TiO(3) solid solution was restricted by x=0.225. Curie points(Tc) of the present glasscceramics were independent of the composition of Ba(l-x)Ca(x)TiO(3), however temperature coefficients of Σ were lowered by the addition of increasing amount of CaO. Frequency dependencies of dielectric constant and loss tangent were examined in the frequency range from 1 k to 1 M Hz.
