摘要
By The Conventional Solid State reaction is used to prepared the (ZnFe2O4, NiFe2O4,CuFe2O4) From the Oxide of (Cu, Zn, Ni & ferrous oxalate) while had emphasized the Crystallize Synthesis accurately and Sort by these Synthesis by using the Technique (X.R.D), it is mixedtoFormedthe final Synthesis (Ni1-x-yZnxCuy Fe2O4) with (x= 0.2,0.4,0.6, 0.8) &(y=0.2,0)as pressed pellets are sintered at (1200,1250,1300)C for (2 h) after every once sintered bulks densities and electrical characteristic are measured. The electrical characteristics for these samples, included the measure of D.C current as electrical resistivity () and A.C current as the measure of dielectric constant (),and dissipation factor (tan).
