摘　　要：以纳米NiO和BaTiO3粉为原料,在1100～1200℃烧结温度条件下,制备了NiO/BaTiO3陶瓷复合材料,研究了复合材料的介电性能。结果表明,随NiO加入量的增加,复合材料的介电常数和介电损耗随之降低,而且在10MHz频率附近,复合材料出现了较强的共振吸收现象。NiO/BaTiO3 ceramics composites with different volume fraction of NiO were fabricated at the sintering temperature 1100-1200 ℃, using NiO and BaTiO3 as raw materials. The effect of NiO content on dielectric properties of NiO/BaTiO3 composites was investigated. The results showed that the dielectric constant and dielectric loss of composites decrease with the increase of NiO content. Furthermore, the composites exhibit the intensive resonance absorption as the frequency of the applied electric field is higher than 10 MHz.
