• Forsterite is a candidate ultrahigh frequency dielectric for wireless communications. The quality factor $Q$ of forsterite (Mg2SiO4) for microwave dielectrics is affected by calcination conditions. The shape of calcined powder particles remains the same as that of fine grains of raw silica materials. This is one of the key points for high $Q$, because of the realization of a high green density. From the observation of the section of calcined grains by definition (EPMA), it was clarified that Si ions remain in the core part of the grains. The remaining silica affected $Q$ by forming a glassy phase and enstatite (MgSiO3).
