BORO [6 records]

Record 1 2011-02-11

English

Subject field(s)
  • Chemistry
  • Geochemistry
  • Semiconductors (Electronics)
DEF

A high-melting trivalent metalloid element that is known both in an extremely hard shiny black crystalline form and in the form of a greenish yellow or brown amorphous powder, that occurs in nature only in combination (as in borax and boric acid and as a trace element in plants and animals), ... that is used chiefly in metallurgy (as for increasing the hardenability of steel) and in nucleonics because of its high absorption of neutrons - symbol B.

DEF

The p-type dopant commonly used for the isolation and base diffusion in standard dipolar integrated circuit processing.

French

Domaine(s)
  • Chimie
  • Géochimie
  • Semi-conducteurs (Électronique)
DEF

Métalloïde se combinant facilement avec S, C, Al et réduisant les oxydes métalliques.

CONT

Le bore élémentaire est principalement employé dans l'industrie métallurgique comme désoxydant et dégazifiant [...]. Il s'utilise de plus en plus dans les réacteurs nucléaires et en technique des hautes températures : alliages bore-aluminium, bore dans les matières plastiques comme absorbeur de neutrons [...]

OBS

[Le bore] entre dans la composition de quelques silicates (tourmaline, axinite, etc.) des pegmatites, des filons acides et des dépôts fumerolliens.

CONT

Carbure de bore. En réduisant à l'arc électrique l'anhydride borique par le carbone, on obtient un carbure [...] solide extrêmement dur et à structure complexe.

CONT

Les principaux abrasifs utilisés sont le corindon, le carbure de silicium, le carbure de bore et le diamant.

DEF

Sólido cristalino negro, soluble en álcalis fundidos, insoluble en agua. La inhalación de polvo o partículas es tóxica.

CONT

El carburo de boro, además de ser refractario, es muy eficaz para absorber neutrones térmicos; por eso se usa para hacer las barras de control de ciertos reactores nucleares.

OBS

Fórmula química: B4C
