- Forsterite (Mg2SiO4)
is the magnesium rich end-member of the olivine solid solution
- Forsterite is
associated with igneous and metamorphic rocks and has also been found in
- 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
- 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
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
- 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
- Forsterite crystals,
doped with Cr4+, Cr3+, Cr2+, Co2+, Ni2+, V4+, were grown by Czochralski
- The inherent Kerr
nonlinearity of the Cr:Forsterite laser crystal can be accessed to
generate ultrashort pulses using a technique known as
- 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.
