Antimony telluride

Antimony telluride is an inorganic compound with the chemical formula Sb 2 Te 3.As is true of other pnictogen chalcogenide layered materials, it is a grey crystalline solid with layered structure. Layers consist of two atomic sheets of antimony and three atomic sheets of tellurium and are held together by weak van der Waals forces.Sb 2 Te 3 is a narrow-gap semiconductor with a band gap 0.21 eV Get price

Note that, these points are associated with the standard atmospheric pressure.. Boiling Point – Saturation. In thermodynamics, the term saturation defines a condition in which a mixture of vapor and liquid can exist together at a given temperature and pressure. The temperature at which vaporization (boiling) starts to occur for a given pressure is called the saturation temperature or boiling Get price

Metabolism of tellurium, antimony and germanium

Recently, tellurium (Te), antimony (Sb) and germanium (Ge) have been used as an alloy in phase-change optical magnetic disks, such as digital versatile disk-random access memory (DVD-RAM) and DVD-recordable disk (DVD-RW). Although these metalloids, the so-called exotic elements, are known to be non-essential and harmful, little is known about Get price

Arizona Geology: An Arizona tellurium rush?

According to this USGS document, annual global tellurium production is even lower than 215 tons. FSLR will need to consume about 135 tons of tellurium to produce each 1 GW of solar panel. Their own demand, alone with demands from other applications, will continue to drive tellurium price up. I do not think they can survive a tellurium rush. Get price

Tellurium

Tellurium burns in air with a greenish flame to form TeO2. In the molten state it strongly corrodes metals such as iron and copper. Tellurium vapour consists mainly of Te2 molecules. Applications. The semiconductor properties of tellurium when alloyed with cadmium enable the use of tellurium Get price

Environmental context Tellurium, a chemical element increasingly being used in new technologies, is an emerging contaminant. Our understanding of tellurium's environmental behaviour, however, is poor, with critical knowledge gaps such as its distribution in the various environmental compartments and the environmental fluxes associated with mining, usage and disposal.

Classification Of Minerals

The mineral breithauptite (NiSb) contains nickel and the semimetal antimony, which acts as the electronegative, nonmetallic element of the compound. Breithauptite is thus an antimonide. The mineral calaverite (AuTe2), in turn, contains the metallic element gold and the semimetal tellurium, which provides an anion; calaverite is a telluride. Get price

pared with metals, antimony is a poor conductor of electricity and heat. Along with the other metalloids (arsenic, germanium, silicon, and tellurium), it is positioned in the periodic table along the boundary between metals and nonmetals. Its common oxida-tion states are +5, +3, 0, and -3, although other oxidation states have been recognized. Get price
