5n 99.999% 2-5mm Se Metal Pellet Selenium Granule for Evaporating Selenium Film

1. MAterial Overview

Characteristics:	Dark red - brown to blue black amorphous solid or red clear crystal or metallic gray to black crystal.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 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.

5.Applications

 Electrolytic manganese industry: Selenium is added in the production of electrolytic manganese to enhance the current efficiency.

 Glass industry: Selenium de-colors glass by neutralizing the green color due to the presence of iron. If a red color is desired cadmium sulphoselenide is added. Selenium is also used in the production of privacy glass.

 Agriculture: since selenium is an essential micronutrient for animals it is used in premix for feed additives. It is also added to some special blends of fertilizers.

 Metallurgy: Selenium is added to improve the machinability of carbon steel, stainless steel and copper. It acts as a grain refiner in the grids of low-maintenance lead-acid batteries.

 Pigment: Cadmium sulfoselenide compounds are added in plastics, glass, ceramics and paints for red or orange color.

 Electronic/electrical: Due to infrared light transparency, Selenium is used in windows for infrared optical devices (lenses for CO₂ lasers).

 in solar cells selenium is used in CIGS, CIS and CdSe.
