Synthesis and characterization of Li-ferrite doped Cd-ferrite

Abstract

This paper focused to prepared  complex at Varity compound (x = 0, 1,2,5,10,15, and 20 wt%), by using the solid state reaction. samples disc with diameter 1.5 cm and thickness 0.4cm prepared at temperature 1100  for two hours in air. The x- ray diffraction using to study the structure of all samples and the volume of crystals for composition using sherrer equation according to Hall method. The in dices of lattice increased linearly with increased Li in Li Cd  composites. The electric measurement for complexes in as a function  of frequency with range (50 HZ – 1 M H Z). Real dielectric constant in lower frequency decreased with increased Li content in Li Cd , It found the x= 15% from Li has upper Values at real dielectric constant and decreased with increasing frequency for all complexes prepared. The imaginary of dielectric constant decreased with increased  Li of   samples in lowering frequent and decreased with increased frequency and the concentration x= 15% of Li has upper value at imaginary dielectric constant. The tan  decreased with increased of Li concentration for Li cd  in lower frequency and concentration x= 15% of Li has upper tan Also, the tan, decreased with increased frequency for all samples. The alternative conductivity, will decreased with increased Li concentration in Li Cd  for x = 15% of Li has upper alterative conductivity. We noticed  increased with increased frequency for samples.
