Paper Title:
Synthesis and Magnetic Properties of Polymer Derived Metal/SiCN Ceramic Composites
  Abstract

Metal particles were embedded in a silicon carbonitride (SiCN) matrix, derived from the commercially available polysilazane Ceraset®. Metal powders, such as Fe, Mn, Co, Ni, were mixed and milled with pre-cross-linked polysilazane and subsequent pyrolysis. The metals act as active fillers to increase the density of composite. The phases and microstructures of metal/ceramic composites were studied using XRD, SEM and EDS. The magnetic property was measured with Magnetic Property Measurement System at –196oC and 27oC. The results show that there were two main domains in composites, one was metal-rich domain and another was metal-poor domain. The reaction compound between metal and matrix had great effect on the magnetic properties of composites, filled with different metals.
