Uranium processing BritannicaWhat Chemicals Rust Metal Rapidly Sciencing

Uranium processing preparation of the ore for use in various products Uranium U although very dense 191 grams per cubic centimetre is a relatively weak nonrefractory metal Indeed the metallic properties of uranium appear to be intermediate between those of silver and other true metalsRust is a chemical reaction that involves the exchange of electrons between atoms certain chemicals can accelerate rusting by increasing the electrical activity between iron and oxygen Substances such as salts and acids increase the conductivity of moisture around metal making rust happen more quickly

Making sodium metal at home metallabHow the Electroplating Process Works dummies

Sodium metal is one of the alkali metals which are soft and reactive and have relatively low melting points They do not occur in a free metallic state in nature as they are too reactive Sodium is the most common of them and it is a major component of table salt which is a compound with ChlorineAnd it is found in Sodium hydroxide which is a strong base and used in lyeIn a similar fashion sodium metal and chlorine gas can be produced by the electrolysis of molten sodium chloride Electrolytic cells are also used in a process called electroplatingIn electroplating a more expensive metal is plated deposited in a thin layer onto the surface of a cheaper metal

Potassium WikipediaUSB1 Process for desulfurization of petroleum

Potassium is a silvery white metal that is soft enough to be cut with a knife with little force Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure It was first isolated from potash the ashes of plants from which its name derivSulfur containing petroleum feeds are desulfurized by contacting the feeds with staged addition of sodium metal at temperatures of at least about 250 176 C in the presence of excess hydrogen to sodium metal The formation of Na 2 S is substantially suppressed and the formation of NaSH is promoted in the desulfurization process
