Overview of factory supply bismuth telluride Bi2Te3 CAS 1304-82-1
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.

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 factory supply bismuth telluride Bi2Te3 CAS 1304-82-1
Bismuth Telluride (Bi2Te3), also known as BiTe or Bismuth Telluride Trihydrate, is a fascinating and technologically important material with the chemical formula Bi2Te3 and the CAS number 1304-82-1. This compound belongs to the family of binary compounds, consisting of two elements, bismuth (Bi) and tellurium (Te), in a ratio of 2:3. It is a semiconducting material that exhibits unique properties, making it a sought-after component in various industries.
Bismuth Telluride has been extensively studied for its applications in the field of optoelectronics, particularly in the production of photovoltaic cells and thermoelectric generators. Its bandgap, around 0.2 to 0.3 electron volts, allows it to convert light energy into electrical power efficiently, making it an attractive material for thin-film solar cells. The combination of high efficiency and low cost makes Bi2Te3 an appealing alternative to traditional silicon-based solar cells.
Moreover, Bi2Te3 possesses exceptional thermoelectric properties, which means it can convert temperature differences into electricity. This property makes it suitable for waste heat recovery systems, where it can convert the heat generated from industrial processes into usable electricity. The Seebeck coefficient, a measure of the voltage generated per unit temperature difference, is relatively high in Bi2Te3, making it a promising material for thermoelectric devices.
In addition to its thermoelectric and optoelectronic applications, Bismuth Telluride is also used in spintronics, a branch of electronics that explores the manipulation of electron spin rather than just charge. The material’s ability to control spin-polarized currents opens up new possibilities in data storage and information processing technologies.
The synthesis of Bi2Te3 can be achieved through various methods, including direct melting, solid-state reactions, and even chemical vapor deposition (CVD). The purity and crystal structure of the final product are critical factors, as they directly influence the material’s performance in the intended application. Factory-supplied Bi2Te3, therefore, undergoes rigorous quality control processes to ensure consistent and reliable material properties.
Due to its environmental friendliness, Bi2Te3 is gaining attention as a potential replacement for materials with higher environmental impact. As a non-toxic and abundant element, it offers a sustainable option for the future of electronic and energy conversion technologies.
However, like any material, Bi2Te3 has its limitations. For instance, it can be brittle and sensitive to moisture, necessitating proper encapsulation and handling during manufacturing. Research is ongoing to improve its mechanical properties and develop more stable forms for practical applications.
In conclusion, Bismuth Telluride (CAS 1304-82-1) is a versatile material with significant potential in the realms of optoelectronics, thermoelectrics, and spintronics. Its unique properties, combined with the ability to be produced at scale by factories, make it a valuable resource in the development of next-generation technologies. As researchers continue to explore its full potential, we can expect to see further advancements in the field of semiconductors and energy conversion, driven by this intriguing compound.
