制备条件对纳米晶吸收剂的吸波性能影响的实验研究

Experimental study of the effect of fabrication condition on absorbing property of nano-absorbent

采用柠檬酸盐溶胶凝胶法制备出不同Co掺杂的Ba纳米晶铁氧体吸收剂,分析了制备条件对其物性、吸波性能等的影响,确定了最佳制备工艺条件.研究了粒径对纳米晶吸波性能的影响,同时还测试了纳米晶吸收剂的雷达波吸收性能.结果表明,纳米晶吸收剂是一种性能优良的雷达波吸收材料.

Co-doped nano-absorbent is prepared by the sol-gel method. The effect of the fabrication condition on physical property and absorbing property are analyzed. The optimum fabrication condition is found. The influence of particle size on absorbing property is compared with that of the conventional absorbent. Radar absorbing measurement shows that nano-absorbent has a good absorbing property.
