Description
Colorless, white, yellow, green, or blue solid; [HSDB] White powder; Insoluble in water; [Gelest MSDS]
Sources/Uses
The most abundant mineral with high concentrations of beryllium oxide; Used as a source of beryllium; [HSDB] Of the more than 50 beryllium-containing minerals, only beryl and bertrandite have economic significance. [Reference #1]
Comments
Beryllium is linked to lung cancer from studies of workers with beryllium disease and in a cohort of seven beryllium-processing plants. Higher risks occurred in workers with the highest exposures (hired before 1950). [Reference #1] May cause irritation; [Gelest MSDS] See "Beryllium" and linked occupational diseases.
