Project @ a Glance

  • Forsterite (Mg2SiO4) is the magnesium rich end-member of the olivine solid solution series.
  • Forsterite is associated with igneous and metamorphic rocks and has also been found in meteorites.
  • Forsterite is named for the German naturalist, Johann Forster. It is one of two minerals that are simply known as olivine and the other mineral is fayalite.
  • Forsterite is a crystalline magnesium silicate. It is best known for having, like the other magnesium silicate, clinoenstatite, with the formula MgSi03 or MgO.SiO2, an extremely low electrical conductivity. This makes forsterite ceramics the ideal substrate materials for electronics.
  • Forsterite has been synthesized by solid-state reaction between MgO and SiO2,6 or bauxite and MgCO3,7 but also by various sol-gel methods,2,8,9 which include a H2O2-assisted process.
  • Refactory forsterites are widespread components of all types of unequilibated chondrites. The origin of refractory forsterites, have been traced by conducting an in-situ LA-ICP-MS trace element study of refractory forsterites from carbonaceous chondrites.
  • During weathering of forsterite and tephroite under the humid, tropical conditions of the Ivory Coast, intermediate Mg,Fe 3 or Mn2+-smectites appear prior to widespread development of iron or manganese oxyhydroxides.
  • Silicate impurity phases within the MgO aggregates are bright yellow CL monticellite and bright pink-red CL forsterite identified by CL microscopy.
  • Cr:forsterite is an appealing gain medium in the near infrared. The output is compatible with telecommunications wavelengths and its gain bandwidth makes it a good alternative to Ti:Sapphire systems for longer wavelength configurations.
  • The ternary system diopside forsterite enstatite (CaMgSi2O6 Mg2SiO4 MgSiO3) shows phase relations among the three most important minerals of the upper mantle and has long been employed as a basis for modeling the generation and crystallization of basaltic magmas and the compositional trends of their residues
  • Forsterite crystals, doped with Cr4+, Cr3+, Cr2+, Co2+, Ni2+, V4+, were grown by Czochralski technique.
  • The inherent Kerr nonlinearity of the Cr:Forsterite laser crystal can be accessed to generate ultrashort pulses using a technique known as self-modelocking.
  • Thin films of forsterite are synthesised in order to monitor in situ, by infrared transmission spectroscopy technique, the crystalline to amorphous transition during irradiation.
  • A new variety of simulated tanzanite known as "Forsterite" has recently begun to make headway in the retail market.
  • Forsterite is grown in Russia. A member of the olivine mineral group, natural forsterite also exists, and can be found primarily in Sri Lanka.
