dc.description.abstract	The effect of MnO2, Ag2O and CaO on the physical, microstructure and electrical properties of NiO were investigated in this work. Minimum values of water absorption were attained in specimens fired at 1200 οC for 2 hours lead better densification by minimizing the present of closed pores. Maximum values of firing shrinkage were attained in specimens fired at 1200 οC for 2 hours. Results of XRD show Nickel oxide and Nickel Manganese oxide – Ni6MnO8 . SEM of mix (C1), shows exsolution two liquid phase, grain growth, grains pelt shape, melt phase, crystalline phase, exsolution miscibility and Mn enter the lattice of Ni. The relation between I and V for the different mixes show very good plateau in (I-V) relation. Ac conductivity increase with increasing frequency at room temperature.	en_US
