“…Moreover, Mg 2 SiO 4 materials offer the superior properties of high quality factor and low dielectric constant and play an important role as the microwave dielectric materials in the field of wireless communications [7]. In addition, Mg 2 SiO 4 has been used in matrix materials for phosphors owing to its complex crystal structure and the wide absorption and excitation band [8]. Therefore, based on the above applications, extensive studies of Mg 2 SiO 4 synthesis have been conducted during the last twenty years, demonstrating the urgent need for Mg 2 SiO 4 materials.…”

Forsterite (Mg2SiO4) materials have been used in the industrial applications of refractory materials, bone grafting materials, and microwave dielectric materials. In order to avoid the formation of the secondary phase of MgO or MgSiO3, spray pyrolysis with the precursors of magnesium nitrate hydrate and tetraethyl orthosilicate has been applied to synthesized Mg2SiO4 powders. In this study, three typical morphologies of smooth solid sphere, rough hollow sphere, and concaved hollow sphere were observed using scanning electron microscopy and transmission electron microscopy. The experimental results suggested that morphology and particle size distribution are strongly influenced by the calcination temperature. Finally, the corresponding powder formation mechanisms were proposed and discussed.
