Abstract:

Adopting laminated dry pressure molding process, the HH2 (mixing powder of (Zn0.7, Mg0.3)TiO3(ZMT3) and (Ni0.8Zn0.12Cu0.12)Fe1.96O4(NZC) in weight ratio of 1:1) and (Zn0.9, Mg0.1)TiO3(ZMT1) were designed to be interlayer, which was co-fired with ZMT3((Zn0.7, Mg0.3)TiO3) and NZC((Ni0.8Zn0.12Cu0.12)Fe1.96O4) at 900°C to synthesize layer composition. The study of interfacial microstructure SEM and diffusion mechanism shows that the co-fired layer composition could alleviate the interfacial stress and eliminate warp defects resulting from the co-fired process. The interfacial diffusion behavior of co-fired layer composition was researched,which provide a promising solution of warp and distortion resulting from different materials co-fired process.
