Cadmium telluride (CdTe) is a stable crystalline compound formed from cadmium and tellurium. ... CdTe has low acute inhalation, oral, and aquatic toxicity, and is ...
Mercury cadmium telluride is known to be a toxic material, with additional danger from the high vapor pressure of mercury at the material's melting point; in spite of this, it continues to be developed and used in its applications. [6]
Cadmium telluride photovoltaic cells have negative impacts on both workers and the ecosystem. [81] When inhaled or ingested the materials of CdTe cells are considered to be both toxic and carcinogenic by the US Occupational Safety and Health Administration. Workers in processing facilities may be exposed to, and inhale, fine particles or fumes ...
Human toxicity and heavy-metal emissions are particularly important impact factors for thin-film solar cell production, as the potential environmental and health effect of cadmium use has been a particular concern since the introduction of CdTe cells to the commercial market in the 1990s, when the hazards of cadmium-containing compounds were ...
Mercury cadmium telluride is a semiconductor material that is ... Tellurium poisoning is particularly difficult to treat as many chelation agents used in the ...
Cadmium is a naturally occurring toxic metal with common exposure in industrial workplaces, plant soils, and from smoking. Due to its low permissible exposure in humans, overexposure may occur even in situations where only trace quantities of cadmium are found.
Cadmium tellurite is a colourless solid [1] that is insoluble in water. [2] It is a semiconductor. It is part of the monoclinic crystal system, with space group P2 1 /c (No. 14). It can also crystallize in the cubic crystal system and hexagonal crystal system at temperatures above 540 °C. [4] [5]
The telluride ion is the anion Te 2− and its derivatives. It is analogous to the other chalcogenide anions, the lighter O 2−, S 2−, and Se 2−, and the heavier Po 2−. [1] In principle, Te 2− is formed by the two-e − reduction of tellurium. The redox potential is −1.14 V. [2] Te(s) + 2 e − ↔ Te 2−
