The Enhanced Thermal Stability of (MgNi)TiO Dielectric Ceramics Modified by a Multi-Phase Method.

The thermal stability of (MgNi)TiO dielectric ceramics has been improved by mixing with CaTiO phases owing to higher positive temperature coefficients. The pure (MgNi)TiO and the mixture phase systems of CaTiO-modified (MgNi)TiO were verified by XRD diffraction patterns to ensure the crystallite of different phases. The microstructures of the CaTiO-modified (MgNi)TiO were observed by SEM and EDS to investigate the relation between element ratios and grains.
