Tellurium Metal
MATERIAL OVERVIEW
Characteristics: Silvery white, lustrous, solid metal characteristics. Soluble in sulfuric acid, nitric acid, potassium hydroxide and potassium cyanide solution. Insoluble in water. Imparts garlic-like odor to breath, can be depilatory. It is a p-type semiconductor and its conductivity is sensitive to light exposure.
Hazards: (Metal and compounds, as Te): Toxic by inhalation. Tolerance, 0.1 mg/m3 of air.
Application: Tellurium could be used in different fields, according to its purity. It could be used as infrared detector materials, solar cell material, cooling material and so on.
