Titanium’s Discovery Titanium was discovered in 1791 by geologist Reverend William Gregor. He had found black, magnetic sand that looked similar to gunpowder in a stream of Mannacan in Cornell, England. (This sand is now known as Ilmenite, it is made from oxides of Iron and Titanium. Gregor then analyzed this sand and found it to be very magnetite (Fe3O4). He also noticed the impure oxide of a new metal, which he had said to be a “reddish brown calx.” This calx turned yellow when dissolved in sulfuric acid and turned purple when reduced with tin, iron, or zinc. Gregor then knew hehad discovered a new metal and named it Manaccanite.  Klaproth discovered titanium, from Boinik, Hungary. It was exactly like Gregor’s calx. In 1797 Klaproth read Gregor’s account from 1791. He realized that Klaproths titanium and Gregor’s maccanite were the same element and Gregor was the element’s true discoverer. Even though Gregor had discovered the new metal first, scientists preferred the name Titanium. Many scientists tried to obtain a sample of titanium but it took about 119 years from its discovery, until 99.9% of pure titanium was isolated. Metallurgist Matthew Hunter in Schenectady, New York, had the idea of heating titanium (IV) chloride with sodium to red-heat in a pressure cylinder in 1910.
 * The boiling point of Titanium is 3,287 degrees C
 * The Melting point of Titanium is 1,660 degrees C
 * The Density of Titanium is 4.54 grams per cubic centimeter
 * Titanium has 22 protons, 26 neutrons, and 22 electrons
 * Titanium has an atomic mass of 47.867
 * The atomic number of Titanium is 22
 * The electron configuration is 1s2 2s2 2p6 3s2 3p6 3d2 4s2
 * Titanium has 4 valence electrons

 In 1936, titanium was now a commercial production because of the Kroll process. (Kroll process- heating titanium (IV) chloride with [|magnesium] ) By 1948 worldwide production had reached about 3 tons a year. Cost of pure Titanium is about $661.00 per 100g.

<span style="color: black; font-family: 'Times New Roman','serif'; font-size: 19px;">Titanium oxide (TiO2) is a pigment for white paint and this is the largest use of the element. Pure titanium oxide is clear and is used to create titania, an artificial gemstone. Titanium tetrachloride (TiCl4), another titanium compound is used to make smoke screens. code <span style="color: black; font-family: 'Times New Roman','serif'; font-size: 19px;"> "Titanium."
