摘要

The Bi and Zn substitution effects on the sintering behaviors, magnetic and electric properties of hexagonal ferrites with a composition of 2(Ba_(1-x)Bi_xO).2(Zn_yCo_(0.8-y)Cu_(0.2)O).6(Fe_(2-x/3)Zn_(x/3)O_3) were investigated. The results showed that the addition of Bi and Zn can significantly promote Co_2Y densification. The Y phase may be triggered to decompose into M and spinel phases at high sintering temperatures (above 1050°C) for samples with excess Bi (x=0.2) substitution, which resulted in densification and magnetic properties degradation. Co_2Y ferrites with x = 0.1 and y = 0.4 sintered at 1050°C show a relative density of 94%, a high initial permeability of 4.5, a quality factor (Q) of 50.
