Enhanced infrared radiation properties of CoFe2O4 by doping with Y3+ via sol–gel auto-combustion
Source abstract
Abstract
Abstract CoFe 2− x Y x O 4 ( x =0, 0.05, 0.10, 0.15, 0.20, 0.25) ferrites were synthesized using a sol–gel auto-combustion method. The auto-combustion behavior of the dried gels and the effects of the Y 3+ content and the sintering temperature on the infrared radiation properties of CoFe 2− x Y x O 4 ferrites were investigated by FTIR, TG/DSC, SEM and XRD techniques. The results showed that the CoFe 2− x Y x O 4 dried gels exhibited an auto-combustion behavior at room temperature once they were ignited in air. The Y 3+ content and the sintering temperature were the two important parameters for enhancing the infrared radiation properties of CoFe 2− x Y x O 4 ferrites, reflected by the crystalline phase and the lattice strain. The highest infrared emissivity of 0.95±0.01 was obtained from CoFe 1.80 Y 0.20 O 4 after sintering at 600 °C for 2 h, which was 4.40% higher than that of CoFe 2 O 4 .
