초록
The sintering behavior of BaFe12O19 with the addition of one and three weight % of CuWO4 as a liquid phase sintering aidis studied. Samples are sintered in the temperature range 900-1250 oC and the effect of CuWO4 addition on density,microstructure, phase composition and magnetic properties is examined. Compared to BaFe12O19 with no sintering aidaddition, addition of 1 wt % CuWO4 retards densification. Addition of 3 wt % CuWO4 promotes densification at lowersintering temperatures but retards densification at temperatures > 1050 oC. Three wt % CuWO4 addition induces theformation of BaWO4 and Ba3WFe2O9 secondary phases at temperatures ≥ 1100 oC. Addition of CuWO4 causes a decrease insaturation magnetization, remanent magnetization and coercivity.
Abstract
The sintering behavior of BaFe12O19 with the addition of one and three weight % of CuWO4 as a liquid phase sintering aidis studied. Samples are sintered in the temperature range 900-1250 oC and the effect of CuWO4 addition on density,microstructure, phase composition and magnetic properties is examined. Compared to BaFe12O19 with no sintering aidaddition, addition of 1 wt % CuWO4 retards densification. Addition of 3 wt % CuWO4 promotes densification at lowersintering temperatures but retards densification at temperatures > 1050 oC. Three wt % CuWO4 addition induces theformation of BaWO4 and Ba3WFe2O9 secondary phases at temperatures ≥ 1100 oC. Addition of CuWO4 causes a decrease insaturation magnetization, remanent magnetization and coercivity.
