What is Titanium?
The symbol for the metal titanium in the Periodic Table is Ti, which is a direct abbreviation of the metal’s name. The metal was discovered in Great Britain—Cornwall to be exact—by a clergyman and mineralogist named William Gregor in 1791. However, Gregor did not actually get to name the element—at least not as it is commonly recognized today: that honor was taken by Martin Klaproth, a German chemist who had discovered uranium and zirconium two years prior and who would later go on to discover cerium in 1803. Klaproth discovered titanium independently of Gregor in 1793 and, unaware that it was the same substance identified by Gregor, named it titanium after the Greek gods the Titans, because in his view it was “the incarnation of natural strength” (“History of Titanium”). Gregory had named it “gregorite” two years before and needless to say Klaproth’s appellate is what stuck.
Regardless, titanium was not actually isolated for more than another century—in 1910. Titanium thus occurs naturally as part of chemical combinations. It is most often found in rutile and ilmenite, and it is actually the ninth most common element in the earth’s crust,...
As the 22nd element on the Periodic Table, it has a weight of 47.867amu and a low density of 4510 kg/m3, which is about 60% lower than the density of steel (“History of Titanium”). It is very corrosion-resistant with a high passivity and it is also nontoxic and thus is used in medical implants in humans.
Klaproth discovered his titanium source in a sample of rutile, which he had obtained from Boinik, and also from a sample of manaccanite, which is what Gregor discovered his in (Krebs). The reason it took so long to isolate titanium is because the process to do so is costly. The element can be isolated by heating with carbon, as is done in the process of iron smelting, because the element then binds with the carbon to create titanium carbide (Emsley). It was not until 1932 that William Kroll, the metallurgist famous for developing the Kroll method of isolating titanium for commercial purposes, showed that it could be extracted from ore by reducing titanium tetrachloride with calcium—and then later magnesium and sodium, which is the process still used mainly in the commercial isolation of titanium today (Krebs).

Archaeology After brushing off all the debris, the team of archaeologists lifted the time capsule with a great sense of satisfaction and placed it on the research table. Inside we found five items that will enhance our understanding of life in the United States of America, circa 1969. The first two items we unearthed from the time capsule were bundled together using a piece of rough twine. The larger of the
"In the case of arms trafficking," they advise, "there are arms dealers eager to sell AK-47s to conflict zones all over the world. There are shipping and air transport services willing and able to transport the weapons to warlords who are destabilizing much of West Africa. The warlords trade diamonds for guns, and the arms brokers and transporters in turn launder the diamonds with brokers in Antwerp and deposit
International Regulation of Tourism in Antarctica Since the mid-1980s, Antarctica has been an increasingly popular tourist destination, despite the relative danger of visiting the largest, least explored -- and arguably least understood -- continent on earth. Beginning with the 1959 treaty establishing Antarctica as an international zone free of claims of sovereignty by nation's that had been instrumental in establishing research stations there, there has been almost constant negotiation about how
The student has provided research on various vibration analytic techniques such as the use of Laser Vibrometry for Damage Detection using Lamb Waves in discovery processes to detect microcracks. Outcome 3. The Information Literacy competency was satisfied through the research efforts made by the student through data gathering regarding aircraft structures and vibrations qualification techniques retrieved from the MIL-STD-810F and NASA Langley Research Laboratory. Techniques include Fatigue Damage Spectrum (FDS)
Standard Construction of Modern High Field Magnets Used in Modern Nuclear Magnetic Resonance Devices Nuclear magnetic resonance devices are playing an increasingly important role in healthcare and research today. As the term implies, magnets, specifically high field magnets, are an essential part of these sophisticated devices with important implications for a wide range of valuable healthcare and research applications. To gain additional insights into how these devices operate, this paper
Peri-Implantitis Infections of the implantation area the mainly widespread of the dental implant complications. Implant infection is a state which is known as peri-implantitis which has a sign of swelling or inflammation of the tissues adjacent to the implantation area. Peri-implantitis is a type of periodontal disease that is able to result to inflammation, bone loss and failure in dental implant in any case it is not treated appropriately. A flame
