制备研究了掺杂锰、钴、镍的含锌铁磁体/碳复合纳米材料,使用傅里叶变换红外光谱仪采用KBr压片法测试了它们在波长2.5～25μm的红外透过率,根据朗伯-比尔定律计算了质量消光系数.结果表明:锰锌铁磁体/碳复合材料和钴锌铁磁体/碳复合材料随着焙烧温度的升高质量消光系数先增大后降低;锰锌铁磁体/碳复合材料于800℃焙烧后在8～14μm波段质量消光系数能达0.1 m2/g.700℃焙烧后,钴锌铁磁体/碳复合材料质量消光系数在3～5μm波段达0.2 m2/g,在8～14μm波段能达0.25 m2/g;镍锌铁磁体/碳复合材料在焙烧后其8～14μm远红外波段的消光性能得到加强,质量消光系数达0.17 m2/g,但是3～5μm波段质量消光系数由原来的0.5 m2/g降低到了0.15 m2/g.
Preparation of zinc-doped ferromagnetic / carbon composite nanomaterials doped with manganese, cobalt and nickel was studied. The infrared transmittance of the ferrite magnets / carbon composites doped with manganese, cobalt and nickel was tested by using KBr method with Fourier transform infrared spectroscopy at 2.5-25μm wavelength. - Beer’s law was used to calculate the mass extinction coefficient.The results showed that the mass extinction coefficient of Mn-Zn ferrite / carbon composites and Co-Zn ferrite / carbon composites first increased and then decreased with increasing calcination temperature; Mn-Zn ferrite / After calcined at 800 ℃, the mass extinction coefficient of Co-Zn ferrite / carbon composites reaches 0.2 m2 / g in the wavelength range of 3-5 μm after the mass extinction coefficient of 8-14 μm band can reach 0.1 m2 / g at 700 ℃. In the range of 8 ~ 14μm, it can reach 0.25 m2 / g. The extinction performance of the nickel-zinc-iron magnet / carbon composites in the far-infrared range of 8 ~ 14μm after firing is enhanced with a mass extinction coefficient of 0.17 m2 / g. The mass extinction coefficient was reduced from 0.5 m2 / g to 0.15 m2 / g.
