| 摘 要： | 采用机械合金化方法制备了纳米晶LiFe5O8和Life4.994Nd0.006o8材料，并研究了它们的吸波性能。实验结果表明，LiFe5o8在7－12GHz频段内有三个吸收峰，但吸收值较低，当加入少量的Nd2O3后，吸收值增大，吸波性能得到有效的提高，将LiFe4.994Nd0.006O8与少量的Fe粉混合，吸收值增大，频带展宽，其吸波性能得到进一步的提高，它是一种有发展前景的吸波材料。

| Abstract: | LiFe5O8 and LiFe4.994Nd0.006O8 nanocrystalline powders were synthesized by mechanical alloying. Their absorption properties were studied. Three lower absorption peaks between 7GHz and 12GHz exhibit for LiFe5O8 material. When adding Nd2O3 to it,the absorption is effectively increased. Adding few Fe powders to LiFe4.994Nd0.006O8 results a further increase in absorption and bandwidth. So this material proves to be prospective for wave absorption application. |
