Yttrium Carbonate Trihydrate: Yttrium (atomic symbol: Y, atomic number: 39) is a Block D, Group 3, Period 5 element with an atomic weight of 88.90585.  The number of electrons in each of yttrium's shells is [2, 8, 18, 9, 2] and its electron configuration is [Kr] 4d¹ 5s². The yttrium atom has a radius of 180 pm and a Van der Waals radius of 219 pm. Yttrium was discovered by Johann Gadolin in 1794 and first isolated by Carl Gustav Mosander in 1840.

Yttrium Carbonate Trihydrate: In its elemental form, Yttrium has a silvery white metallic appearance. Yttrium has the highest thermodynamic affinity for oxygen of any element. Yttrium is not found in nature as a free element and is almost always found combined with the lanthanides in rare earth minerals. While not part of the rare earth metals it resembles the heavy rare earths which are sometimes referred to as the "yttrics" for this reason.

Yttrium Carbonate Trihydrate: Another unique characteristic derives from its ability to form crystals with useful properties. The name yttrium originated from a Swedish village near Vaxholm called Yttbery where it was discovered.Yttrium Carbonate Trihydrate is a water insoluble yttrium source that can easily be converted to other yttrium compounds, such as the oxide, by heating (calcination). Most materials can be produced in high and ultra high purity forms.

Yttrium Carbonate Trihydrate: Yttrium Carbonate is widely applied in electronic ceramics, glass, and electronics. High purity grades are the most important materials for tri-bands Rare Earth phosphors and Yttrium-Iron-Garnets, which are very effective microwave filters. Yttrium compounds are used as a catalyst for ethylene polymerization. Yttrium is used in the production of a large variety of synthetic garnets, and Yttria is used to make Yttrium Iron Garnets, which are very effective microwave filter
