Ceramic. -Highly crystalline giant dielectric CaCu3Ti4O12 (CCTO) is prepared by combustion of a stoichiometric Me-O-(CH 2)2-OH solution of the metal nitrates and inexpensive TiO2 followed by sintering of the obtained CCTO powder (1050 C, 30 h). The route is superior to other sol-gel routes involving expensive Ti alkoxides, oxynitrates, or chlorides. The formation of the cubic perovskite CCTO is confirmed by XRD. With average grain sizes of 1.5-5 m, the material shows an optimum dielectric constant (' 43325) with a low dielectric loss (tan 0.088) at 10 kHz and 25 C. The dielectric relaxation behavior is rationalized from impedance and modulus studies, and the presence of a non-Debye type of relaxation is confirmed. -(SINGH, L.; KIM, I. W.; WOO, W. S.; SIN, B.
