BÉRYLLIUM, Minerais Encyclopædia Universalis

24/03/2020· Minerais. Peu abondant et très dispersé dans la nature, le béryllium se trouve sous forme de composés plus ou moins complexes : silicates (béryl, phénacite), aluminate (chrysobéryl), oxyde (bromellite), phosphate (béryllonite). Le seul minerai utilisé industriellement est le béryl.

Béryllium — Wikipédia

Le béryllium est un élément chimique de symbole Be et de numéro atomique 4. Dans le tableau périodique, il est le premier représentant des métaux alcalino-terreux. Le nom béryllium vient du grec βήρυλλος (beryllos) qui désignait l'aigue-marine ou l'émeraude. Élément bivalent, le béryllium est un métal alcalino-terreux d'aspect gris acier. Il est léger, fragile et toxique

Beryllium Mineral Information Data And Localities. Beryllium is extracted from the beryllium silicate ore by either sintering or melting into a soluble mixutre. The sintering process uses sodium fluorosilicate and soda at around 770 C 1,420 F to create sodium fluoroberyllate which is then decomposed to beryllium hydroxide with water.

After separation, beryllium spheres of 97 percent purity are obtained. The excess magnesium undergoes further treatment and burned off in a vacuum furnace, thereby leaving beryllium of 99.99 percent purity. The beryllium spheres can be converted by isostatic pressing to beryllium powder which is useful in various beryllium alloys.
