Overview of Factory Supply Cas 99.99% Bi2te3 Powder Bismuth 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 Factory Supply Cas 99.99% Bi2te3 Powder Bismuth 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 Factory Supply Cas 99.99% Bi2te3 Powder Bismuth Telluride
Bismuth Telluride (Bi2Te3), also known as Bismuth Telluride Trioxide, is a fascinating and versatile material that finds applications in various sectors due to its unique electronic properties and thermal stability. It is an inorganic compound composed of two atoms of bismuth (Bi) and three atoms of tellurium (Te), forming a crystal structure with remarkable characteristics.
At a purity level of 99.99%, the factory-supplied Bi2Te3 powder exhibits exceptional quality, ensuring high performance in the devices and technologies it supports. The near-perfect purity allows for minimal impurities, which directly contributes to better efficiency and reliability. This grade is commonly sought after by researchers, manufacturers, and engineers working in the fields of optoelectronics, photovoltaics, and thermoelectricity.
The chemical formula Bi2Te3 implies that the compound possesses a rock salt structure, where bismuth ions (Bi3+) are surrounded by an octahedron of tellurium ions (Te6+). This structure gives rise to its characteristic metallic luster and a relatively high melting point, around 545°C, making it suitable for applications that require heat resistance.
One of the key features of Bi2Te3 is its excellent thermoelectric properties. It converts temperature differences into electrical voltage, making it a potential candidate for waste heat recovery and power generation systems. Its high Seebeck coefficient, or thermopower, combined with relatively low thermal conductivity, makes it attractive for thermoelectric generators and coolers.
In the realm of optoelectronics, Bi2Te3 has shown promise as a topological insulator, a material that behaves as an insulator in its bulk but conducts electricity on its surface. This property opens up possibilities for applications in spintronics, quantum computing, and ultra-sensitive sensors.
Furthermore, Bi2Te3 is used in thin-film solar cells, where it forms part of tandem structures, enhancing overall cell efficiency by absorbing different ranges of the solar spectrum. Its high absorptivity and tunable bandgap make it a valuable material in photovoltaic technology.
When it comes to processing, the 99.99% pure Bi2Te3 powder is easily handled and processed into various forms, such as thin films, powders, or even nanostructures, depending on the desired application. It can be synthesized through methods like flux growth, solid-state reactions, or even mechanical milling, each tailored to achieve the required particle size and morphology.
In summary, Factory Supply’s 99.99% Bi2Te3 powder is a premium material with exceptional properties, ideal for harnessing its thermoelectric, optoelectronic, and photovoltaic capabilities. Its high purity ensures reliable performance and versatility across a range of industries, from energy conversion to advanced electronics. As research and development continue to push the boundaries of these materials, the demand for high-quality Bi2Te3 powder will likely remain strong.
