Preparation and Electromagnetic Properties of Al₂O₃/Ni Composites

Abstract:

In this paper, a series of Al₂O₃/Ni composites with various content of Ni (0 vol%, 10 vol%, 20 vol%, 30 vol%, 40 vol% and 50 vol%) were prepared, and the effect of the methods and compositions on the density and electromagnetic properties was investigated. The results show that the density of the composites increases with the increasing sintering temperature as well as the increasing content of Ni. Moreover, the dielectric constant of the composites increases remarkably with the sintering temperature and the content of Ni, while the permeability shows an almost linear enhancement with the increase of Ni content. This suggests that the Al₂O₃/Ni composite can be expected to be a promising substrate material with certain electromagnetic compatibility.
