We made this in cutting edge national level laboratory with rigorous process and restrictive standard. This item is not only for retail selling but bulk order is very welcome as well. Due to Indium is soft yet easy to be melted while cutting, this Indium cube is made by hand with painstaking effort. Based on its natural characteristic, it is vulnerable been scratched. Even fingernail pressing could marking on surface. So, please take care avoid placing with sharp items. This item would NOT accept return or refund, if you are perfectionist please don’t purchase it, thanks for understanding. 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 Indium is a chemical element with symbol In and atomic number 49. Indium is the softest metal that is not considered to be an alkali metal. It is a silvery-white metal that resembles Tin(Sn) in appearance. It is a post-transition metal that makes up 0.21 parts per million of the Earth's crust. Indium has a melting point higher than sodium and gallium, but lower than lithium and tin. Chemically, indium is similar to gallium and thallium, and it is largely intermediate between the two in terms of its properties. Indium was discovered in 1863 by Ferdinand Reich and Hieronymous Theodor Richter by spectroscopic methods. They named it for the indigo blue line in its spectrum. Indium was isolated the next year. Indium is a minor component in zinc sulfide ores and is produced as a byproduct of zinc refinement. It is most notably used in the semiconductor industry, in low-melting-point metal alloys such as solders, in soft-metal high-vacuum seals, and in the production of transparent conductive coatings of indium tin oxide (ITO) on glass. Indium is considered a technology-critical element. In 1863, the German chemists Ferdinand Reich and Hieronymous Theodor Richter were testing ores from the mines around Freiberg, Saxony. They dissolved the minerals pyrite, arsenopyrite, galena and sphalerite in hydrochloric acid and distilled raw zinc chloride. Reich, who was color-blind, employed Richter as an assistant for detecting the colored spectral lines. Knowing that ores from that region sometimes contain thallium, they searched for the green thallium emission spectrum lines. Instead, they found a bright blue line. Because that blue line did not match any known element, they hypothesized a new element was present in the minerals. They named the element indium, from the indigo color seen in its spectrum, after the Latin indicum, meaning 'of India'.Richter went on to isolate the metal in 1864. An ingot of 0.5 kg (1.1 lb) was presented at the World Fair 1867. Reich and Richter later fell out when the latter claimed to be the sole discoverer. Shipment：All of our small parcels are fulfilled the eBay's mandatory shipment policy. Items would be carried by eBay designated carrier, SpeedPAK, to most of supporting countries. Its official declaration of delivery efficiency is very similar to ePacket.ePacket via China Post: about 11-66 days to most of countries. Our average records are 7 to 21 days to North America. Parts of west coastal cities in America has the best record like 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)All three above are national carriers in our region. Once it dispatches abroad, it would be delivered by your local national post like USPS, Canada Post, Australia Post, Royal Mail, or Deutsch Post, etc.DHL: about 3-7 days (individual countries or even longer)Note: If DHL doesn’t support service to certain areas or countries, we would switch EMS to ship your item.
