A metallic element, symbol Cr, which does not occur in the free state, is remarkable for the brilliant colours of its compounds, has the atomic number 24, the atomic weight 51. 996, is part of the group VIB of the Periodic Table, and is used as an alloying and plating element on metal and plastic substrates for corrosion resistance, in chromium-containing and stainless steels, as a protective coating for automotive and equipment accessories, in nuclear and high-temperature research and as a constituent of inorganic pigments.

OBS

chromium metal: expression used by the US Occupational Safety and Health Administration (OSHA).

OBS

chromium: term adopted by Environment Canada; used in the list of pollutants measured in the National Air Pollution Surveillance Network (NAPS).

DEF

Corps simple de symbole Cr, de numéro atomique 24 et de poids atomique 51,9961, habituellement bi, tri ou hexavalent, qui, en raison de sa résistance à la corrosion de l'atmosphère et de certains agents chimiques, de sa haute dureté et de sa résistance à l'usure, est employé couramment en revêtement pour la protection des aciers et d'autres métaux.

OBS

chrome : terme retenu par Environnement Canada; utilisé dans la liste des polluants mesurés par le Réseau national de surveillance de la pollution atmosphérique (RNSPA).

Record 2 2010-03-02

English

Subject field(s)
  • Plastics Manufacturing
  • Medical and Surgical Equipment
DEF

A cast which is produced by injecting a hollow organ with plastic, allowing it to polymerize and then corroding the surrounding tissue, and which is used to prepare specimens for scanning electron microscopes. [Source: Cell and Tissue Research, 1984.]

CONT

Table I shows some example measurement made from corrosion casts from rat heart and hamster lung under several different conditions..... While the primary application of vascular corrosion casting has been and likely will remain in the elucidation of the 3-dimensional distribution of vessels in tissue and organs, high quality casts also yield valuable quantitative information about that vasculature.... the corrosion casting method [can] be used to describe or measure the internal volume of any hollow or porous structure or material as long as methods are available to remove the surrounding material and leave the cast intact.

CONT

Kidney glomerulus corrosion cast scanned with confocal microscope.

OBS

Incorporation of marker substances in the casting resin (e.g. isotopes, heavy metals, electron dense materials, photosensitive materials, or fluorescent substances) to enhance quantitative measurements are also being considered in some laboratories.

French

Domaine(s)
  • Plasturgie
  • Équipement médico-chirurgical
CONT

[...] couches de silicone sur des copies en cire obtenues par moulage de corrosion de corps humains non fixés.
