| Agent Name | Beryl |
|---|---|
| CAS Number | 1302-52-9 |
| Formula | Al.3/2Be.3H2-O3-Si |
| Major Category | Mineral Dusts |
| Synonyms | Beryl ore; Beryllium aluminium silicate; Beryllium aluminosilicate; Beryllium aluminum silicate; Natural beryl; [ChemIDplus] UN1566 |
| Category | Other Mineral Dusts |
| 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. |
