what are some fun facts about titanium?

Titanium was discovered in 1791 by Mr.Gregor, but it was not named until 1795.  It was first isolated by Hunter in 1910, by heating TiCl4 with sodium in a steel bomb at temperatures from 700-800 C.  That's pretty hot!\n\nTitanium is the ninth most abundant metal in the earth's crust.  That's a lot of titanium!\n\nIt is only about $6 to buy a pound of titanium. That's less than going to the movies! That's more like popcorn and pop at the movies.  heck, I'd just get some titanium.\n\natomic number: 22\n\natomic mass: 47.867 g\n\ncommon oxidation states: 2,3,4\n\nphysical appearance:  a beautiful lustrous white metal\n\nmelting point: 1660 degrees C \n\nboiling point: 3287 degrees C\n\ncrystal structure: hexagonal closest packed\n\n density: 4507 kg m3\n \n\nelectronegativity: 1.54 Pauling units\n\nground state electron configuration: [Ar]3d24s2

The TI-83! It's probably not the one with the fastest processor or the best features, but I love mine all the same and will keep writing silly little games in TI-BASIC until the end of High School...

Ti(4+) = 18 electrons.\nSo the atom, which forms a stable compound without forming an ion, is first of all an inert gas and has 18 protons and electrons. that's argon.\n\nHope this helps=)

Titanium with special alloy bolts so saltwater doesn't corrode. Light weight for its strength.\nSome deep sea are silica glass. The strength increases as the compressive loads are applied.\nCheck Jacques Cousteau. He made some special deep diving.\nWoods Hole Oceanographic Institute has Alvin.

Metal detectors either sense distortions in magnetic fields, or nuclear density- Titanium is one of the most non-magnetic metals, and is quite light (low nuclear density).

There is a HUGE amount of infomation on metallurgy out there, but if you want an interesting search, try searching out why the HUBBLE Space Telescope failed - there was some deformed metal and the reason the optics tests passed before launch is an interesting story about materials, optics and people.\n\nI'm a metallurgist, and of all the exotic materials it turns out steel has the greatest range of properties (from annealed iron all the way up to ball bearing steel and stainless).  Titanium is interesting stuff (good for corrosion and medium temps (500°F-1000°F), but aluminum can have the highest density-to-strength ratio.  Research on how tungsten filaments are made is interesting too.  \n\nMark Twain said that a metallurgy student would learn more making his own pocket knife by digging the ore out of the ground, refining it into steel, and fabricating the knife than he would by book learning - do you have a passion you're particularly interesting in?  Learning about something you're interested in is effortless.\n\nAnother optics subject of interest is what is currently going on in semiconductor photolithography - they are reaching the limits of what can be done with light and refractive materials (CaF lenses) and immersion lithography (see link below).

Chrome-moly steel has a density of 7.9g/cc, with an ultimate strength of 520MPa, and a modulus of 200GPa. \n\nTitanium (Ti3Al2.5v) has a density of 4.48g/cc, ultimate strength of 620Mpa, and modulus of 100GPa. \n\nThis means that the titanium is a lot lighter (over 40%), a little stronger (20%), but less stiff (by 50%). A titanium frame will flex a bit more than a steel frame, but that acts as a shock dampener and makes the ride a lot more comfortable. \n\nAluminum (assuming generic) has a density of about 2.8g/cc, ultimate strength of 425MPa, and a modulus of 73GPa. \n\nSo aluminum is actually a lot lighter than titanium, but it is weaker and less stiff (more flexible). \n\nHowever, these numbers are bulk properties, and do not take into account design differences with bike frames. A titanium bike frame will usually be lighter than an aluminum bike frame because you don't have to use as much metal to get the same strength and stiffness with titanium as you would have to do with aluminum and steel. \n\nIt's a LOT more expensive, so unless this is for a racing bicycle, a titanium frame will not be worth the expense.

Some of the commonly used bio materials\n\n1.Synthetic materials currently in use include metal alloys, ceramics, and polymers. \n2.Metals :\na. used for load-bearing implants such hip and knee prostheses, and wires, pins, screws for fracture fixation, and also cvascular stents.\nb.pure metals have been used, but alloys offer advantages in strength nd corrosion-resistance.\nc.three major alloys include stainless steel, cobalt-chromium-molybdenum alloys, and titanium alloys\nd.Selection criteria should include biocompatibility, appropriate mechanical properties, corrosion, and cost.\n\nPS:Common metals used in implants—either as pure elements or as alloys (mixture of metals)—include titanium, platinum, iridium, gold, iron (as stainless steel alloy), vanadium, cobalt, aluminum (ceramic) and zirconium (ceramic).  The advantage of alloys over metals is that the properties of the material can be fine-tuned to its application needs. Changing the elements and their concentrations present in the alloy leads to stronger, more flexible materials.\n\nFound a great site. Definitely go through it.\nhttp://biomed.tamu.edu/biomaterials/Metals.htm

I plan on keeping mine in for the rest of my life with no rusting.  I would think that in a few million years if they find even my bones decayed away, that titanium will still be sittin' there shining nice and pretty.

Because the metal reacts with air at high temperatures it can not be produced by reduction of its dioxide. Titanium metal is therefore produced commercially by the Kroll process; a complex, and expensive batch process developed in 1946 by William Justin Kroll. In the Kroll process, the oxide is first converted to chloride through carbochlorination, whereby chlorine gas is passed over red-hot rutile or ilmenite in the presence of carbon to make TiCl4. This is condensed and purified by fractional distillation and then reduced with 800 °C molten magnesium in an argon atmosphere.\n\nA newer process called the FFC Cambridge Process may displace this older process. This method uses the feedstock titanium dioxide powder (which is a refined form of rutile) to make the end product which is either a powder or sponge. If mixed oxide powders are used, the product is an alloy at a much lower cost than the conventional multi-step melting process. It is hoped that the FFC Cambridge Process will render titanium a less rare and expensive material for the aerospace industry and the luxury goods market, and will be seen in many products currently manufactured using aluminium and specialist grades of steel.\n\nTitanium may be purified to ultra high purity in small quantities by the van Arkel deBoer process by reacting with iodine and decomposing the formed vapors over a hot filament to pure metal.\n\nTitanium oxide is produced commercially by grinding its mineral ore and mixing it with potassium carbonate and aqueous hydrofluoric acid. This yields potassium fluorotitanate (K2TiF6) which is extracted with hot water and decomposed with ammonia, producing an ammoniacal hydrated oxide. This in turn is ignited in a platinum vessel, which creates pure titanium dioxide.\n\nCommon titanium alloys are made by reduction. For example; cuprotitanium (rutile with copper added is reduced), ferrocarbon titanium (ilmenite reduced with coke in an electric furnace), and manganotitanium (rutile with manganese or manganese oxides) are reduced.
