Effects of $Nb_2O_5$ and $V_2O_5$ Additions on the Sintering Behavior and B-H Loop Properties of Lithium Ferrite

ABSTRACT

ed at about 100$0^{circ}C$(d:4.6g/㎤) and 85$0^{circ}C$(d:4.5g/㎤) in the specimens with the addition of $Nb_2O_5$ and $V_2O_5$ respectively. The addition of $Nb_2O_5$ retulted in a large and uniform grain size, and the addition of $V_2O_5$ resulted in a uniform grain size but the final density was lower than that of the pure specimen. The squareness was increased and the coercive force was decreased by the addition of $Nb_2O_5$, and the squareness was decreased and the coercive force was increased by the addition of $V_2O_5$. These effects could be explained by a large and uniform grain size, and by a lower final density of specimens with the addition of $Nb_2O_5$ and $V_2O_5$ respectively.
