Nickel ferrite (NiFe2O4) nanopowder has been synthesized by a sol-gel auto-combustion process and further sintered at various sintering temperatures. The samples were characterized XRD, SEM VSM. Enhancement of apparent density the sample observed with increase in temperature great influence on magnetic dielectric properties NiFe2O4. results reveal that grain size increases increasing temperatur...

Calcium doped nickel ferrite powders have been prepared by sol-gel combustion technique. Metal nitrates, such as calcium nitrate, nickel nitrate and ferric nitrate, were used as the source materials and citric acid and polyvinyl alcohol were used as the burning agent and agglomeration reducing agent, respectively. The average crystallite size of the prepared ferrite was in the order of ~70- 92 ...

The CuFeCr0.5Ni0.5O4 (CFO) compound was synthesized using sol–gel reaction combustion technic. structural analysis showed that the obtained composites have a polycrystalline nature and cubic spinel structure ( $${\text{Fd}}\bar{3}m~$$ space group). Microstructural revealed formation of spherical elongated grains our sample. dielectric electrical transport properties were investigated in detail ...

Abstract In this study, we presented two reliable methods, the sol–gel and autocombustion, to synthesis a high purity BiFeO 3 single phase with low calcination time using glycine as chelating agent. The glycine-autocombustion method produced either or concentrations of reactants (Bi(NO ) + Fe(NO ), while glycine-sol–gel delivered reactants. case tartaric acid urea agents, mixtures Bi 25 FeO 40 ...
