As a result, iron is deposited on the surface of the cathode due to a difference in an ionization tendency, and high purity iron can be obtained. TOHO ZINC CO.,LTD. is producing and selling electrolytic iron refined by the wet process on an industrial scale. TOHO ZINC CO.,LTD. accounts for the top market share of high purity iron in wet type ...

High-purity irons (e.g. electrolytic iron) are more resistant to corrosion. Because it hardens platinum and palladium alloys, ruthenium is used in electrical contacts, where a thin film is sufficient to achieve the desired durability. With its similar properties to and lower cost than rhodium, electric contacts are a major use of ruthenium.
In this system, high-purity wrought iron, charcoal, and glass were mixed in a crucible and heated until the iron melted and absorbed the carbon. [28] Iron chain was used in Indian suspension bridges as early as the 4th century. [29] Wootz steel was produced in India and Sri Lanka from around 300 BC. [28]
Pig iron, also known as crude iron, is an intermediate good used by the iron industry in the production of steel. It is developed by smelting iron ore in a blast furnace . Pig iron has a high carbon content, typically 3.8–4.7%, [ 1 ] along with silica and other dross , which makes it brittle and not useful directly as a material except for ...
Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications, sometimes for direct ...
EPR Properties is a turnaround play right now, appealing only to a small group of more aggressive investors. It is also focused on a unique niche -- experiential properties -- that history has ...
