Abstract

The influence of sintering temperature on microstructure and electrical properties of Zn doped CaCu₃Ti₄O₁₂ ceramics were investigated. The CaCu_3-xZn_xTi₄O₁₂ (x=0, 0.06, 0.1, 0.2) ceramics were prepared by sol-gel method, and sintered at 950 ·, 1000 ·, 1050 ·, 1100 ·. XRD patterns confirm the formation of CCTO crystal phase in the as-prepared samples, and SEM results showed different porous structures and grain sizes at different temperatures. The results were commented and discussed on the temperature effect on electric properties and microstructure of CaCu_3-xZn_xTi₄O₁₂ ceramics.
