Research Results For 'Ferrous'

TUBE ALLOYS

Tube alloys was the codename of Britain's development of its first atomic bomb. The then British prime minister, Attlee, never allowed discussion of the project in cabinet, not trusting his ministers, and kept the cost of the project - 100 million pounds - secret from the British Public. Ironically, a secretary at the British Non-Ferrous Metals research Association - Melita Norwood - was a Soviet spy and kept the USSR fully informed with plans and details. The Russians knew more about Britain's first atomic bomb than most of the British government.

INDIAN RED

Indian red is a deep red, purplish-brown pigment prepared by the calcination of crystalline ferrous sulphate. Indian red possesses good staining and spreading abilities and opacity. It is permanent and will mix with other pigments.

MORDANT

A mordant is an adhesive compound capable of uniting with dye-stuffs to form insoluble pigments, and thus, if the reaction is made to take place in the fibres of a fabric, fix the colour in it. Mordants are mostly used in cotton and wool dyeing, and also in gilding to attach gold leaf and in paints intended for non-ferrous metal surfaces so as to etch the surface and provide better adhesion for the pigment.

PHOSPHORIC ACID

Phosphoric acid can exist as a crystal or clear liquid. It is an oily, thick, colourless, and odourless liquid, or a thick, colourless, unstable crystalline solid. It is used in the manufacture of phosphates, such as salts, soaps, and detergents; fertilizers; yeasts; fire control agents; opal glass; electric lights; dental cements; waxes and polishes; gelatin; ethylbenzene, propylene, and cumene; and soft drinks. It is used as an acid catalyst, soil stabilizer, antioxidant in food, acidulant and flavour agent in jellies and preserves, bonding agent for refractory bricks, and petrol additive. It is also used in the rust proofing and polishing of metals, cotton dyeing, tile cleaning, extracting penicillin, hot stripping for aluminium and zinc substrates, ceramic binding, water treatment, process engraving, electro-polishing, coagulating of rubber latex, operating lithography and photoengraving operations, and pickling. It is used to manufacture the phosphoric acid electrolyte fuel cell system which has created the largest fuel cell built and has been used to treat lead poisoning.

Phosphoric acid is incompatible with strong caustics and most metals. It readily reacts with metals to form flammable hydrogen gas. The liquid can solidify at temperatures below 21 degrees C. It is corrosive to ferrous metals and alloys. It is soluble in alcohol and hot water. It can form three series of salts: primary phosphates, dibasic phosphates, and tribasic phosphates. It is deliquescent and hygroscopic. It is a chelating agent. It has a low vapour pressure at room temperature. Phosphoric acid is also known as orthophosphoric acid, metaphosphoric acid, and white phosphoric acid.

PRUSSIAN BLUE

Prussian blue (also formerly known as Berlin Blue) is a blue pigment discovered by Diesback (known as the Prussian) of Berlin in 1710. It is prepared by precipitating a ferric salt, such as ferrous sulphate, with a solution of potassium ferrocyanide. Prussian blue vaies from a slightly greenish blue to a blue tinged with violet and has a characteristic bronze lustre. Prussian blue has an intense colour and great staining strength but its noted for its transparency. Prussian blue is resistant to acid, but vulnerable to alkali.

ROSANILINE

Rosaniline is a base compound of many aniline dyes. It is a basic compound prepared by oxidising a mixture of aniline and toluidine by nitro-benzene in the presence of ferrous chloride. Rosaniline itself is a colourless solid, but if converted into a salt by the addition of an acid, it loses water and becomes coloured.

RUST

Rust is the product of the corrosion of iron or steel, due largely to electrolytic action. Rust consists mainly of hydrated ferric oxide with some basic ferrous or ferric carbonates also present.

TURNBULL'S BLUE

Turnbull's Blue is a pigment produced by the action of a ferrous salt on potassium ferri-cyanide.

VENETIAN RED

Venetian Red is a permanent red pigment composed of ferric oxide originally found naturally in Italy, then later obtained by igniting ferrous sulphate.
