摘要：

Zinc titanate (ZnTiO3) powders of perovskite structure were synthesized by conventional solid state reaction using metal oxides. Powders of ZnO and TiO2 in a molar ratio of 1:1 were mixed in a ball mill and then heated at temperatures from 700 to 1000degreesC for various time periods in air. The crystallization temperature of ZnTiO3 powder was similar to820degreesC, activation energy for crystallization was similar to327.14 kJ/mol and for grain growth was similar to48.84 kJ/mol. A transition point was observed when the electrical resistivity was measured versus temperature. Like some ferroelectric materials, a PTCR behavior above the transition temperature was observed with Curie temperature of similar to5 degreesC. (C) 2004 Elsevier Ltd and Techna S.r.l.
