A telluride is a compound of the element tellurium and one or more other elements. For example, the mineral calavarite is mostly gold telluride (AuTe 2 ). At one time, gold was found in chunks or nuggets large enough to see. People mined gold by picking it out of streams and rivers...
The present invention is aimed to provide an electroless gold plating solution which requires less amount of a reducing agent, retains a sufficient deposition rate for a practical use, and has an excellent stability as a plating solution; and a method for carrying out an electroless gold plating...
Gold is a chemical element; it has symbol Au (from Latin aurum 'gold') and atomic number 79. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reacti...
Gold is a chemical element with the symbol Au (from Latin: aurum, "shining dawn") and an atomic number of 79. It has been a highly sought-after precious metal for coinage, jewelry, and other arts since the beginning of recorded history. The metal occurs as nuggets or grains in rocks, ...
Metallic element of atomic number 79, Group IB of the periodic table, aw 196.9665, valences of 1, 3;no stable isotopes. 3.2 Description Gold does not have a distinctive odor at room temperature,but when heated it emits a sweet odor that is detected withdifficulty. Chloroauric acid composed ...

Smelting is the process by which a metal is obtained either as an element or as a simple compound, from its ore by heating beyond the melting point with the presence of oxidizing agents such as flux. In other words, smelting is the process of applying heat to ore in order to extract a...
Low Energy Nuclear Reaction (LENR) using nickel and hydrogen is a clean, very very cheap, and super abundant energy technology, but can it also be used for transmutation? Nuclear transmutation is the conversion of one chemical element into another. ...
A superelastic alloy exhibiting shape memory or pseudoelastic it properties contains about 46.17 weight percent Au and about 53.83 weight percent In. Such alloys containing the superelastic Au—In2 intermetallic compound which exhibits elasticity can be formed into a gasket or seal that can be deforme...
These complexes are prepared by adding polyamine A to a solution of a trivalent gold compound, e.g., AuCl3, then by adding an alkali or ammonium sulfite which results in the precipitation of the desired complex. For preparing a gold sulfite bath from this complex, the latter must be reduce...
