Product Description
MATERIAL OVERVIEW
| Characteristics: | Amorphous red powder, becoming black on standing and crystalline on heating; vitreous and colloidal forms may be prepared. Amorphous form softens at 40 °C and melts at 217 °C. It rarely occurs in its elemental state in nature, or as pure ore compounds. Soluble in concentrated nitric acid and in (liquid form) common alkalies. Forms binary alloys with silver, copper, zinc, lead, etc. Low toxicity. A necessary nutritional factor for animals. |
| Hazards: | Selenium salts are toxic in large amounts, but trace amounts are necessary for cellular function. |
| Applications: | Selenium could be used in different fields, according to its purity. Selenium is now used in a variety of applications, from glass and metallurgical applications to pigments, agriculture and electronics. |
