Overview of CAS 1327-50-0 ANTIMONY (III) TELLURIDE

Telluride and selenide compounds play a significant role in the field of semiconductors, particularly in the development of advanced electronic and optoelectronic devices. These materials belong to the chalcogenide family, characterized by their ability to form compounds with elements from groups IV-VI in the periodic table.


Tellurides: Compounds containing tellurium (Te) as the chalcogen. Examples include cadmium telluride (CdTe), mercury telluride (HgTe), and zinc telluride (ZnTe). These materials have found applications in solar cells, infrared detectors, and high-speed electronics due to their tunable bandgap, high electron mobility, and good thermal stability.


Selenides: Similar to tellurides, but with selenium (Se) replacing tellurium. Notable examples are cadmium selenide (CdSe), gallium selenide (GaSe), and zinc selenide (ZnSe). Selenide compounds are widely used in light-emitting diodes (LEDs), laser diodes, and solar cells due to their direct bandgap properties and efficient light absorption/emission capabilities.

Feature of CAS 1327-50-0 ANTIMONY (III) TELLURIDE

Direct Bandgap: Many telluride and selenide semiconductors have direct bandgaps, which facilitate efficient light emission and absorption processes. This makes them suitable for optoelectronic applications such as LEDs and lasers.


Tunable Bandgap: The bandgap of these materials can be adjusted by alloying or altering the composition (e.g., CdSe to CdTe), enabling customization for specific device requirements across a wide spectrum of wavelengths.


High Electron Mobility: Materials like HgCdTe exhibit high electron mobility, which is crucial for high-speed electronic devices and low-noise detector applications.


Thermal Stability: Some tellurides and selenides, like ZnTe and ZnSe, demonstrate good thermal stability, making them suitable for high-temperature operation and processing.


Non-Toxic Alternatives: With increasing environmental concerns, there’s a push towards exploring less toxic alternatives to commonly used semiconductors. For instance, Cd-based tellurides and selenides are being replaced or combined with less toxic elements like Mg or Mn in some applications.

Parameters of CAS 1327-50-0 ANTIMONY (III) TELLURIDE

Antimony(III) Telluride, also known by its chemical formula CAS 1327-50-0, is a compound formed from the combination of antimony (Sb), an element in Group 15 of the Periodic Table, and tellurium (Te), another element found in Group 16. This inorganic substance holds significant interest due to its unique properties and applications in various industrial sectors.

Tellurium, with atomic number 52, is a rare, brittle, lustrous metalloid that exists naturally in trace amounts in the Earth’s crust. It exhibits semiconducting properties and has been used in photovoltaic cells and electronic devices. Antimony(III) Telluride, on the other hand, is formed when three atoms of antimony combine with two atoms of tellurium, resulting in the chemical formula Sb2Te3.

The compound is known for its unique crystal structure, which typically forms in a rhombohedral or monoclinic lattice. This arrangement gives it high melting and boiling points, making it relatively stable under normal conditions. The interatomic bonds between antimony and tellurium are covalent, contributing to its strength and rigidity.

Antimony(III) Telluride has gained prominence as a thermoelectric material, a property that allows it to convert temperature differences into electrical energy. It has a high Seebeck coefficient, meaning it generates a strong voltage in response to temperature changes, making it suitable for use in thermoelectric generators and power devices. This property makes it particularly attractive for waste heat recovery systems and portable electronic devices, where efficient energy conversion is crucial.

In addition to its thermoelectric applications, Sb2Te3 has been employed in the field of optoelectronics due to its ability to absorb light and emit electrons when excited. This property enables the use of Antimony(III) Telluride in infrared detectors, solar cells, and even as a component in some optical coatings.

However, Antimony(III) Telluride is not without challenges. It can be toxic and corrosive, requiring proper handling and disposal procedures. Furthermore, the synthesis process can generate hazardous byproducts, necessitating environmentally friendly methods for production.

Despite these concerns, research continues to explore ways to improve the performance and safety of Antimony(III) Telluride. Scientists are working on optimizing its composition, nanostructuring, and doping with other elements to enhance its thermoelectric efficiency and expand its potential uses.

In conclusion, Antimony(III) Telluride, CAS 1327-50-0, is a fascinating material with unique properties that make it valuable in several technological applications, particularly in thermoelectric and optoelectronic devices. Its versatility and potential for waste heat recovery make it an important component in the pursuit of sustainable energy solutions. However, ongoing efforts to address its toxicity and environmental impact are essential for its wider adoption and future growth in industry.
