Titanium - Encyclopedia.com
Titanium was one of the first elements to be discovered by modern chemists. The "modern" chemistry period begins after the middle of the eighteenth century. That period is chosen because it is the first time that the basic concepts of modern chemistry were developed. Titanium was discovered by English clergyman William Gregor (1761-1817).
Mineral Resources from the Ocean | Encyclopedia.com
Placer Gold, Tin, Titanium, and Diamonds. Placer deposits are accumulations of resistant and insoluble minerals that have been eroded from their original locations of formation and deposited along river courses or at the ocean margins. The most important of these deposits contain gold, tin, titanium, and diamonds.
William Gregor | Encyclopedia.com
William Gregor1761-1817 English mineralogist famous for discovering titanium. Gregor analyzed a black sand he found in Menacchan, Cornwall. The sand contained iron, manganese, and another substance that Gregor successfully extracted but could not identify. He published his findings in 1791 and proposed the name menacchanine for this new mineral.
Callaway, Ely, Jr. | Encyclopedia.com
In Palms Springs, California, in 1983, Callaway found a small company in financial trouble that was making a fine golf club; the club was old-fashioned looking, with a big hickory shaft, with a titanium-metal rod core. Callaway quickly invested $2.5 million, bought out the company, gave it his name, and his great courage of promotion.
Aluminum - Encyclopedia.com
A titanium-diboride-graphite compound shows significant promise. Among the benefits expected to come when this new technology is perfected are elimination of the greenhouse gas emissions and a 25% reduction in energy use during the smelting operation.
Zirconium Oxide - Encyclopedia.com
Zirconium is located below titanium, which it resembles, in the periodic table. Below zirconium is hafnium, a chemical twin of zirconium. An important use of zirconium is in nuclear power plants. Its most important compound is zircon, which has a number of industrial applications.
Cast Iron Stove - Encyclopedia.com
Cast Iron StoveBackgroundA cast iron stove is a device, built from a material consisting of iron mixed with carbon, in which a solid fuel such as wood or coal is burned to produce heat for warmth or cooking.
Martin Heinrich Klaproth - Encyclopedia.com
Working with minerals from all parts of the globe, Klaproth discovered or codiscovered zirconium (1789), uranium (1789), titanium (1792), strontium (1793,) chromium (1797), mellitic acid (1799), and cerium (1803) and confirmed prior discoveries of tellurium (1798) and beryllium (1798).
Martin Heinrich Klaproth - Encyclopedia.com
He confirmed or independently discovered strontium (1793), titanium (1795), chromium (1798), tellurium (1798), and cerium (1803), always being careful to credit the original discoverers. Klaproth also pioneered the chemical analysis of antiquities, and his conversion to Antoine Lavoisier's new chemistry greatly influenced that theory's ...
Transition Elements - Encyclopedia.com
These elements include titanium, vanadium, manganese, zirconium, molybdenum, palladium, and tungsten. One member of the transition family deserves special mention. Technetium (element #43) is one of only two "light" elements that does not occur in nature. It was originally produced synthetically in 1937 among the products of a cyclotron reaction.
