Research Results For 'Cadmium'

CADMIUM YELLOW

Cadmium yellow is a pigment prepared from the sulphide of cadmium. It is of an intense yellow colour, and possesses much body.
Research Cadmium Yellow

CADMIUM

Cadmium is a comparatively rare element related to zinc, and occurring in some zinc ores. It is a bluish-white metal, both ductile and malleable with the symbol Cd. It was discovered by Stromeyer in 1817, who named it from its association with zinc or zinc ore. Cadmium is used as the basis of a number of pigments.

CADMIUM RED

Cadmium red is a pigment comprising a compound of cadmium, sulphur and selenium. It is a brilliant red pigment, very opaque with good staining power, fast to light and unaffected by exposure to sulphur fumes and resistant to heat.

CADMIUM YELLOW

Cadmium yellow is a compound of cadmium and sulphur, of an intense yellow colour, used as a pigment.

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.

DUCTILITY

Ductility is the property of solid bodies, particularly metals, which renders them capable of being extended by drawing, while their thickness or diameter is diminished, without any actual fraction or separation of their parts. On this property the wire-drawing of metals depends. The following is nearly the order of ductility of the metals which possess the property in the highest degree, that of the first mentioned being the greatest; gold, silver, platinum, iron, copper, zinc, tin, lead, nickel, palladium, cadmium. The ductility of glass at high temperatures seems to be unlimited, while its flexibility increases in proportion to the fineness to which its threads are drawn.

ERYTHROSINE

Erythrosine (Disodium 2-(2,4,5,7-tetraiodo-3-oxido-6-oxoxanthen-9-y1) benzoate monohydrate mixed with other colouring matters which contain arsenic, lead, mercury cadmium and other heavy metals) is a red powder used in the food industry as a red dye.
