Research Results For 'Titanium'

HARRIS M-95

The Harris M-95 Ultra Light is an American bolt-action sniping rifle produced in .50 Browning machine-gun calibre which it takes from a 10 or 20 round magazine. The Harris M-95 has a titanium receiver and carbon-steel 29 inch long barrel and glass-fibre stock. The Harris M-95 is designed for ranges up to 2000 metres.

HARRIS TITANIUM MOUNTAIN RIFLE

The Harris Titanium Mountain Rifle is an American bolt-action hunting rifle produced in calibres to choice which it takes from a 3-5 round magazine depending upon calibre. The Harris Titanium Mountain Rifle has a titanium receiver and 26-inch long carbon-steel barrel and glass-fibre stock. The
Harris Titanium Mountain Rifle is not fitted with sights, but takes a telescopic sight instead.

DIAMAGNETIC

Diamagnetic is a term applied to substances which, when under the influence of magnetism and freely suspended, take a position at right angles to the magnetic meridian, that is, point east and west. From the experimennts of Faraday it appears that all matter is subject to the magnetic force as universally as it is to the gravitating force, arranging itself into two great divisions, the paramagnetic and diamagnetic. Among the former are iron, nickel, cobalt, platinum, palladium, titanium, and a few other substances; and among the latter are bismuth, antimony, cadmium, copper, gold, lead, mercury, silver, tin, zinc, and most solid, liquid, and gaseous substances. When a paramagnetic substance is suspended freely between the poles of a powerful horse-shoe magnet it points in a line from one pole to the other, which Faraday terms the axial line. On the other hand, when a diamagnetic substance is suspended in the same manner it is repelled alike by both poles, and assumes an equatorial direction, or a direction at right angles to the axial line.

KRYPTON

Krypton, named from the Greek word kryptos, meaning 'hidden', is an odourless, colourless, tasteless, non-toxic, monatomic, and highly stable gaseous element of the noble gases group with the symbol Kr. The concentration of Krypton gas in the atmosphere by volume is 1.1 x 10-4. Traces of krypton are present in minerals and meteorites, but the usual commercial source is the atmosphere, which contains 1.14 parts per 106 by volume. Krypton also is formed by the nuclear fission of uranium triggered by slow neutrons: this source may be expected to become increasingly important because of the growing number of fission-power plants.

Krypton has isotopes of every mass number from 74 through 95; six, with mass numbers 78, 80, 82, 83, 84, and 86, are stable. After it has been stored a few days, krypton obtained by nuclear fission contains only one radioactive isotope, krypton-85, which has a half-life of about 10 years, because all the other radioactive isotopes have half-lives of three hours or less. Because its boiling point is about 30 degrees C higher than those of the major constituents of air,
krypton is readily separated from liquid air by fractional distillation; it accumulates along with xenon in the least volatile portion. These two gases are further purified by adsorption onto silica gel, redistillation, and passage over hot titanium metal, which removes all impurities except other noble gases.

Krypton gas liquefies at -152.30 degrees C and freezes 4 degrees C lower. When a current of electricity is passed through a glass tube containing krypton at low pressure, a bluish white light is emitted. The wavelength of an orange-red component of light emitted by stable
krypton-86, because of its extreme sharpness, served as the international standard for the metre from 1960 to 1983. (One metre equals 1,650,763.73 times the wavelength of this line).
Krypton gas is principally shipped and used in gaseous form for excimer lasers, light bulbs, window insulation and Research and Development laboratory research.

LITHOPONE

Lithopone is a mixture of zinc sulphide and barium sulphate used as a white pigment in paints. It is a very pure white with a high degree of opacity, ranking next to titanium white in opacity. Lithopone disintegrates rapidly when exposed, and as such is only used for interior paints.

TITANIUM

Titanium is a metal element with the symbol Ti.

TITANIUM DIOXIDE

Titanium dioxide (also known as titanium white) is a substance used as a very strong white pigment produced from the mineral limonite. It is a brilliantly pure white with enormous staining strength. Titanium dioxide is chemically inert and does not react with oil or varnish media of high acidic value and is resistant to chemicals in the atmosphere.

VACUUM PUMP

A vacuum pump is a device for removing air from laboratory apparatus. The pump may be required because the materials to be handled are air-sensitive or because a low pressure is needed--for example, in vacuum distillation. A reliable vacuum can be obtained using a motor-driven oil pump. For very low pressures, the additional use of a mercury vacuum pump is required, in which a diffused jet of mercury vapour is injected at the inlet port and drives gas molecules towards the outlet. Another low-pressure pump is the turbo-molecular pump, basically a very high-speed turbine. In a 'getter' pump, a film of some active substance such as titanium is deposited in the evacuation chamber and reacts chemically with any gas molecules present, thus removing them from the chamber.

ZIEGLER PROCESS

The Ziegler process is an industrial process for manufacturing high-density polyethylene using catalysts of titanium(IV) chloride (TiCl4) and aluminium alkyls (e.g. triethylaluminium, Al(C2H5)3). The process was introduced in 1953 by the German chemist Karl Ziegler. It allowed the manufacture of polyethylene at lower temperatures (about 60 degrees C) and pressures (about 1atm) than used in the original process. Moreover, the polyethylene produced had more straight-chain molecules, giving the product more rigidity and a higher melting point than the earlier low-density polyethylene. The reaction involves the formation of a titanium alkyl in which the titanium can coordinate directly to the pi bond in ethene. In 1954 the process was developed further by the Italian chemist Giulio Natta, who extended the use of Ziegler' s catalysts (and similar catalysts) to other alkenes. In particular he showed how to produce stereospecific polymers of propene.

ANATASE

Picture of Anatase

Anatase is one of the crystalline forms of titanium oxide, and an important source of the metal titanium. Anatase has the formulae TiO2 and a relative hardness of 6. It is found in granite, gneiss, mica schist, metamorphic limestone, and dolomite. Anatase may be present as an accessory mineral in the rocks or in a quartz vein traversing it. It is used as a coating for welding rods and as a source of titanium.
