Scandium metal ingot - one troy ounce - .995 bullion Scandium was discovered by Lars Fredrik Nilson in and named for the Latin form (Scandia) of Scandinavia in 1879. Scandium is a very rare, lightweight, corrosion resistant metal that is stronger than aluminum and can be alloyed in small amounts to improve the properties of aluminum, particularly in aerospace applications. It is also used in high intensity lamps, laser systems, and solid oxide fuel cells. It is a transition metal but is also considered a rare earth metal as it is usually found with other rare earth elements and has similar properties. It is estimated that only about 2 tonnes of scandium is mined worldwide each year in the form of scandium oxide and that less than 100 pounds of scandium metal is produced worldwide each year. It (and its family of rare earth metals) sits atop the British Geologic Survey's Risk list (see below link). Inscribed on our ingots are the chemical symbol (Sc), purity (99.50%), weight (one troy ounce), and a serial number (this number is unique and will vary). On the reverse is our logo. These are among our largest one troy ounce ingots, each measuring about 30 mm in diameter and 15.5 mm in height. They are over 7 times the size of our osmium and iridium ingots. Like our other ingots they are lightly polished. Scandium will oxidize in air with a yellow or pink hue (ours have a slight yellowish hue as seen in the one pictured). As with our other rare earth metals we've chosen to offer this one as oxidation is not typically a problem, though we do recommend you store your rare earth metals in a cool, dry place. They are well formed but can have tiny edge dings, faint scratches and other minor imperfections. Weight and purity are guaranteed by Rare World Metals Mint. Scandium in the solid form we supply is considered safe. Powder or fine turnings of scandium can ignite in air. As we suggest with all of our metals please keep them in a safe place, do not ingest, and keep out of the reach of children. Each ingot will be shipped with an assay certificate and every shipment will include our velvet logo bag. If you are not completely satisfied with any purchase from us, you have 30 days to return it for a full refund (buyer to pay return shipping). Domestic shipping is free for all orders over $199 (enter code free shipping at checkout). For orders of $199 or under, domestic shipping is $9.95. International shipping is via DHL, FedEx, or USPS international express and costs $45 for shipments up to a pound (9 one ounce ingots or less including packaging materials) and $10 for each additional pound. International customers please be aware that your country may levy import duties and/or VAT taxes on your purchase from us. We have nothing to do with this and cannot pay it for you. If you refuse our package because of this extra cost we will take it back and will refund your order in full once received minus the cost of the return shipping. If you are unsure what these import costs will be please check with your country's customs office. https://en.wikipedia.org/wiki/Scandium http://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth%27s_crust https://nora.nerc.ac.uk/id/eprint/513472/1/Risk_List_2015_FINAL.pdf
