Cobalt is a chemical element with the symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Cobalt-based superalloys have historically consumed most of the cobalt produced. The temperature stability of these alloys makes them suitable for turbine blades for gas turbines and aircraft jet engines, although nickel-based single-crystal alloys surpass them in performance. Cobalt-based alloys are also corrosion- and wear-resistant, making them, like titanium, useful for making orthopedic implants that don't wear down over time. The development of wear-resistant cobalt alloys started in the first decade of the 20th century with the stellite alloys, containing chromium with varying quantities of tungsten and carbon. Alloys with chromium and tungsten carbides are very hard and wear-resistant. Batteries: Lithium cobalt oxide (LiCoO2) is widely used in lithium-ion battery cathodes. The material is composed of cobalt oxide layers with the lithium intercalated. During discharge (i.e. when not actively being charged), the lithium is released as lithium ions. Nickel-cadmium (NiCd) and nickel metal hydride (NiMH) batteries also include cobalt to improve the oxidation of nickel in the battery. As a catalyst: Several cobalt compounds are oxidation catalysts. Cobalt acetate is used to convert xylene to terephthalic acid, the precursor of the bulk polymer polyethylene terephthalate. Typical catalysts are the cobalt carboxylates (known as cobalt soaps). They are also used in paints, varnishes, and inks as "drying agents" through the oxidation of drying oils. The same carboxylates are used to improve the adhesion between steel and rubber in steel-belted radial tires. In addition they are used as accelerators in polyester resin systems. Historical significance: Before the 19th century, cobalt was predominantly used as a pigment. It has been used since the Middle Ages to make smalt, a blue-colored glass. Smalt is produced by melting a mixture of roasted mineral smaltite, quartz and potassium carbonate, which yields a dark blue silicate glass, which is finely ground after the production. Smalt was widely used to color glass and as pigment for paintings. In 1780, Sven Rinman discovered cobalt green, and in 1802 Louis Jacques Thnard discovered cobalt blue. Cobalt pigments such as cobalt blue (cobalt aluminate), cerulean blue (cobalt(II) stannate), various hues of cobalt green (a mixture of cobalt(II) oxide and zinc oxide), and cobalt violet (cobalt phosphate) are used as artist's pigments because of their superior chromatic stability. Radioisotopes : Cobalt-60(Co-60 or60Co) is useful as a gamma-ray source because it can be produced in predictable amounts with highactivityby bombarding cobalt withneutrons. It producesgamma rays with energies of 1.17 and 1.33MeV. We have a single Cobalt-60 source in our possession. If you'd like to see it, feel free to ask. We don't mind sharing it with you, but it is not for sale. It still has an activity of around 1k/m. Other uses: Cobalt is used in electroplating for its attractive appearance, hardness, and resistance to oxidation. This is what this cobalt was used for. These pure pieces were broken off of a cathode after it stopped working due to metal buildup. You don't get much more life than this. If you'd like to know the impurities, the few and tiny amount that there is, just let me know and I'll list them off for you. I have the analysis stored with these bottles/vials. It is also used as a base primer coat for porcelain enamels. No returns and no refunds. No exceptions! But if there is a problem with your order feel free to contact me and we will make it right. Do not contact eBay! That will only slow things down, nobody will be satisfied and it will take forever to resolve. Don't do that to yourself or us. If you do, it will be the last time that you (or anyone within 20 miles of you) will order from us. I promise. We don't mess around with our products and if you try to mess with us we will not play any games with you. We are here to get people what they need and we work hard to get that done. Waste my time and you'll be cut off forever. No exceptions. You will receive: *1 bottle/vial with the Cobalt metal inside. In this order, you will get anywhere between 11.8g-12.8g, even though the listing is only for 10g. We always send more than advertised, other sellers don't and will send either exactly what you ordered or even less. We want your business and treat you good while they try to screw you. Don't take that risk, buy our pure product and have no worries. That bottle will be sealed with tape and it will have a security seals around said tape and lid. That will be bubble wrapped and placed in a box with the proper warning labels and stickers for shipping. That will be taped shut and shipped via USPS First Class Mail with Tracking.
