Abstract
Forsterite is a magnesium silicon oxide mineral with an olivine structure and a diverse spectrum of applications, ranging from biomedical to optical devices. Controlled purity and crystalline phases are key requirements for such applications, but the literature shows a limited understanding of the synthetic routes that would enable such control, in particular at the nanoscale. In this work, single-phase forsterite nanopowder with a crystallite size of 15.3Â nm was synthesized by reverse strike co-precipitation. A reaction mechanism for the synthesis was proposed based on DSC/TGA analysis and intermediate products. Forsterite pellets using the nanopowder were produced by low-cost cold-pressing and showed high transparency and densities above 93%. The nanosized crystals allowed for lower sintering temperatures and enhanced hardness.
