Cerium is a Block F, Group 3, Period 6 element with an atomic weight of 140.116. The number of electrons in each of cerium’s shells is 2, 8, 18, 19, 9, 2 and its electron configuration is [Xe]4f2 6s2. The cerium atom has a radius of 182.5 pm and a Van der Waals radius of 235 pm. In its elemental form, cerium has a silvery white appearance.
Cerium is the most abundant of the rare earth metals. It is characterized chemically by having two valence states, the +3 cerous and +4 ceric states. The ceric state is the only non-trivalent rare earth ion stable in aqueous solutions. It is, therefore, strongly acidic and moderately toxic. It is also a strong oxidizer.
The cerous state closely resembles the other trivalent rare earths. Cerium is found in the minerals allanite, bastnasite, hydroxylbastnasite, monazite, rhabdophane, synchysite and zircon. Cerium was discovered by Martin Heinrich Klaproth, Jöns Jakob Berzelius, and Wilh elm Hisinger in 1803 and first isolated by Carl Gustaf Mosander in 1839. The element was named after the asteroid Ceres.
Praseodymium is a Block F, Group 3, Period 6 element with an atomic weight of 140.90765. The number of electrons in each of praseodymium’s shells is 2, 8, 18, 21, 8, 2 and its electron configuration is [Xe]4f3 6s2. The praseodymium atom has a radius of 182 pm and a Van der Waals radius of 239 pm.
Praseodymium resembles the typical trivalent rare earths, however, it will exhibit a +4 state when stabilized in a zirconia host. Unlike other rare-earth metals, which show antiferromagnetic and / or ferromagnetic ordering at low temperatures, praseodymium is paramagnetic at any temperature above 1 K. Praseodymium is found in the minerals monazite and bastnasite.
Praseodymium was discovered by Carl Auer von Welsbach in 1885. The origin of the element name comes from the Greek words prasios didymos, meaning green twin.

Sulfides
Inorganic sulfides are ionic compounds containing the sulfide ion S2−. Sulfide compounds can be used in a wide variety of applications including solid-state electrolytes, cathode materials in lithium-ion and thermal batteries, semi-conductors in thermoelectric devices, as part of phosphor compositions, as photovoltaic materials, as pigments, and a variety of other applications. Nanochemazone is a world-leading manufacturer in the production of sulfide compounds with one of the most comprehensive selections of sulfides and extensive sulfide-manufacturing expertise. Most sulfides are manufactured as powders in large batch quantities but certain commercial sulfides are available in large metric-ton quantities. Additionally, Nanochemazone can custom synthesis sulfides that may not be listed in our catalog and can modify sulfides to customer's specifications including producing mixed sulfides, non-stoichiometric compositions, or special purities and particle sizes.
