Investigation Of Magnesium Doped Calcium Copper Titanate (Cacu3ti4o12) On Ca And Cu Site Prepared By Solid State Reaction Method

In this research, the effect of magnesium (Mg) dopant on dielectric properties of CaCu3Ti4O12 (CCTO) was investigated. Undoped CCTO and Mg-doped CCTO on Ca and Cu site (Ca1-xMgxCu3Ti4O12 and CaCu3-xMgxTi4O12 have been prepared by solid state reaction method. Starting materials of CaCO3, CuO, TiO2 an...
