About Gold Oxide Hydrate

Oxide IonGold Oxide Hydrateis a highly insoluble thermally stable Gold source suitable for glass, optic and ceramic applications. Gold oxide hydrate is a red-brown solid that is the most stable oxide of gold, but decomposes at 160 °. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems. They are compounds containing at least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic conductivity. Metal oxide compounds are basic High Purity (99.999%) Gold Oxide (Au2O3) Powderanhydrides and can therefore react with acids and with strong reducing agents in redox reactions. Gold Oxide is also available in pellets, pieces, powder, sputtering targets, tablets, and nanopowder (from American Elements' nanoscale production facilities). Gold Oxide Hydrate is generally immediately available in most volumes. Ultra high purity, high purity, submicron and nanopowder forms may be considered. Additional technical, research and safety (MSDS) information is available.

The number of electrons in each of Gold's shells is 2, 8, 18, 32, 18, 1 and its electron configuration is [Xe]4f142 5d10 6s1. Gold Bohr ModelThe gold atom has a radius of 144 pm and a Van der Waals radius of 217 pm. Gold was first discovered by Early Man prior to 6000 B.C. In its elemental form, gold has a metallic yellow appearance. Gold is a soft metal and is usually alloyed to give it more strength.Elemental Gold It is a good conductor of heat and electricity, and is unaffected by air and most reagents. It is one of the least reactive chemical elements. Gold is often found as a free element and with silver as a gold-silver alloy. Less commonly, it is found in minerals as gold compounds, usually with tellurium.
