This Scandium cube is light and soft, easily get yellow when exposing in atmosphere. Based on its natural characteristic, it is vulnerable been scratched. Thus, please take care avoid placing with sharp items. All sales are final, this item would NOT accept return or refund. If you are perfectionist please don’t purchase it, thanks for understanding.Scandium is present in most of the deposits of rare-earth and uranium compounds, but it is extracted from these ores in only a few mines worldwide. Because of the low availability and the difficulties in the preparation of metallic scandium, which was first done in 1937, applications for scandium were not developed until the 1970s, when the positive effects of scandium on aluminium alloys were discovered, and its use in such alloys remains its only major application. The global trade of scandium oxide is 15–20 tonnes per year.Scandium is a soft metal with a silvery appearance. It develops a slightly yellowish or pinkish cast when oxidized by air. It is susceptible to weathering and dissolves slowly in most dilute acids. It does not react with a 1:1 mixture of nitric acid (HNO3) and 48% hydrofluoric acid (HF), possibly due to the formation of an impermeable passive layer. Scandium turnings ignite in air with a brilliant yellow flame to form scandium oxide.The world production of scandium is in the order of 15-20 tonnes per year, in the form of scandium oxide. The demand is about 50% higher, and both the production and demand keep increasing. In 2003, only three mines produced scandium: the uranium and iron mines in Zhovti Vody in Ukraine, the rare-earth mines in Bayan Obo, China, and the apatite mines in the Kola peninsula, Russia.Because of its rarity, scandium is among the most expensive elements. Price for pure scandium fluctuates between 4000 and 20000 US dollars per kilogram. Meanwhile, the limited market generates a variety of prices at any given time. In 2010, at the peak of the rare-earths shortage, the price of scandium rose to over 15000 US dollars per kilogram, and the widely commercially used scandium oxide (Sc2O3) was selling above 7000 US dollars per kilogram. Since then the limited demand coupled with steady production keeps the price at its 20-year average. For more high purity element cube, welcome to visit our store on eBay via,https://www.ebay.com.hk/str/hugohk/Chemical-Element/_i.html?_storecat=32591958018 Shipment：All of our small parcels strictly fulfilled eBay's mandatory shipment policy. All orders will have a valid tracking number without a shadow of doubt. Items would be carried by eBay designated carrier, SpeedPAK, to most of the supporting countries.

Our average records are 7 to 21 days to North America. Parts of west coastal cities in America have the best record for just 7 to 15 days.EMS via China Post: Similar to the ePacket above.eExpress via Hong Kong Post: about 15-50 days (individual countries or even longer)These three above are national carriers in our region. Once it is dispatched abroad, it would be delivered by your local national post like USPS, Canada Post, Australia Post, Royal Mail, or Deutsche Post, etc. DHL: about 3-7 days (individual countries or even longer).FedEx: As above.UPS: As above.TNT: about 7-20 days (individual countries or even longer).Note: Upon four commercial express services may require extra postage.*Unsupported item: mostly like oversize or the item being an unreasonable return by SpeedPAK before loading on cargo flight. The EP symbol and oversea selling is possessed by Extraordinary Precision Engineering Company (HK)Thank you.
