The third stage at 490[degrees]C was attributed to the degradation of urushiol
praseodymium chelate polymers.
The lattice parameter for biphasic samples still increases with
Praseodymium contents which enables us to conclude that the spinel lattice is not compressed by the secondary phase.

Individual light rare earth element grades, in kilograms per tonne (kg/t) were 0.77 kg/t lanthanum oxide, 2.2 kg/t cerium oxide, 0.26 kg/t
praseodymium oxide, 1.08 kg/t neodymium oxide and 0.28 kg/t samarium oxide.
The rare earth sector covers companies with operations involving exploration, extraction, transport, processing or any other business involving any of the following 17 rare earth elements: Scandium, Yttrium, Lanthanum, Lutetium, Ytterbium, Thulium, Erbium, Holmium, Dysprosium, Terbium, Gadolinium, Europium, Samarium, Promethium, Neodymium,
Praseodymium, and Cerium.
Molycorp Inc (NYSE:MCP), producer of rare earth oxides (REO), has reached a three-year agreement with Hitachi Metals for an undisclosed amount whereby Hitachi will supply Molycorp with rare earth magnetic materials including Didymium (a mix of neodymium and
praseodymium) metal and alloy and Lanthanum Oxide, it declared on Friday.
It is estimated that the Molycorp facility in Mountain Pass, CA largely contains cerium and lanthanum, some neodymium and
praseodymium, and small concentrations of samarium, europium, gadolinium, and yttrium [U.S.
