The Union Carbide and Carbon Corporation was formed on November 1, 1917, from the merger of the Union Carbide Company founded in 1898, the National Carbon Company founded in 1886, Linde Air Products Company, a maker of liquid oxygen at Buffalo confiscated from Gesellschaft für Linde's Eismaschinen AG under the Trading with the Enemy Act of 1917, and the Prest-O-Lite company, manufacturer of ...
Metal-shaping factories across the country depended on cutting tools made of crucible steel through the 1920s, when electric steel furnaces gained prominence." [ 14 ] Three companies which merged to form Crucible into the largest U.S. crucible-steel-producing company were: [ 10 ] [ 15 ]
The district is named for the Virginia Metalcrafters Company, which operated out of the complex from 1925 until 2006 and produced reproduction hardware for historic sites including Colonial Williamsburg, Mystic Seaport, and Old Salem. [2] The building was added to the National Register of Historic Places in 2015. [1]
After some recent intense wildfires in Northern California, scientists tested samples of singed soil and were disturbed by their findings: It was laden with a cancer-causing metal called ...
In nuclear science, nuclei of heavy metals such as chromium, iron, or zinc are sometimes fired at other heavy metal targets to produce superheavy elements; [173] heavy metals are also employed as spallation targets for the production of neutrons [174] or isotopes of non-primordial elements such as astatine (using lead, bismuth, thorium, or ...
The high hardness and corrosion resistance of unalloyed chromium makes it a reliable metal for surface coating; it is still the most popular metal for sheet coating, with its above-average durability, compared to other coating metals. [75] A layer of chromium is deposited on pretreated metallic surfaces by electroplating techniques. There are ...
Chrome plating (less commonly chromium plating) is a technique of electroplating a thin layer of chromium onto a metal object. A chrome plated part is called chrome, or is said to have been chromed. The chromium layer can be decorative, provide corrosion resistance, facilitate cleaning, and increase surface hardness. Sometimes a less expensive ...
