Sep 26, 2016· Trace element concentration profiles of garnet from high pressure/low temperature (HP/LT) lawsonite eclogite from the Motagua Fault Zone in Guatemala display an unusual zonation pattern with a central peak for heavy rare earth elements (HREEs) and depletion towards the rim, but with an atypical additional peak of HREEs at the rim.
Recently, Van Orman et al. (2002a) determined the diffusion kinetics of the rare earth elements Ce, Sm, Dy and Yb in a pyrope garnet (Alm16 Pyr71Gr13) at 28 kb, 1200 – 1400. oC in a pistoncylinder apparatus with the fO. 2 buffered by graphite and the prevailing C .

Particles of gadolinium gallium garnet (GGG) and other gallium garnets with rare‐earth elements larger than Gd were spherical with diameters of ‐2 μm, while particles of garnets with smaller rare‐earth ions (Tb‐Lu and Y) were much smaller (100‐300 nm) with particle size distributed in a quite narrow range.
Related Elements. Neodymium is the most abundant of the rare earths after cerium and lanthanum. Neodymium is found in monazite and bastnäsite ores. It is used to make highstrength neodymium magnets and laser crystal substances like neodymiumdoped yttrium aluminum garnet (also .
act on the rareearth ions(~ 105 Oe). In the present work, we studied the magnetic properties of iron garnets of heavy rare earth elements in fields to 240 kOe. As has been shown in numerous papers (see, for ex ample, l12 J ), a rare earth iron garnet (R3Fe5012) can be represented as consisting of three magnetic sublattices:
