Rare earths | Institute for Rare Earths and Metals
The individual rare earth complexes R3 + form rectangular bands with a minimum overlap of adjacent bands. The given rare earth solution is collected and the R3 + ion is precipitated from the solution with oxalic acid. The rare earth oxalate is converted to the oxide by heating in air to 800-1.000 ° C (1.472-1.832 ° F). Solvent extraction

Catalog of Earth Satellite Orbits
Two medium Earth orbits are notable: the semi-synchronous orbit and the Molniya orbit. The semi-synchronous orbit is a near-circular orbit (low eccentricity) 26,560 kilometers from the center of the Earth (about 20,200 kilometers above the surface). A satellite at this height takes 12 hours to complete an orbit.

History and Future of Rare Earth Elements
The rare earths are 17 metallic elements, located in the middle of the periodic table (atomic numbers 21, 39, and 57–71). These metals have unusual fluorescent, conductive, and magnetic properties—which make them very useful when alloyed, or mixed, in small quantities with more common metals such as iron. Geologically speaking, the rare ...
