Overview of Silver Powder CAS 12002-99-2 High Purity Ag2Te Powder Silver Telluride Powder
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 Silver Powder CAS 12002-99-2 High Purity Ag2Te Powder Silver Telluride Powder
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 Silver Powder CAS 12002-99-2 High Purity Ag2Te Powder Silver Telluride Powder
Silver Telluride (Ag2Te) powder, also known as Silver Telluride Silver Powder or CAS No. 12002-99-2, is a high-purity inorganic compound that finds its applications in various industries due to its unique properties. This compound consists of silver (Ag) and tellurium (Te) atoms forming an ionic bond, resulting in a silvery-gray crystalline structure.
The primary characteristic of Ag2Te is its high purity, which ensures minimal impurities and consistent performance in the intended applications. The high purity level is crucial for maintaining its optical, electronic, and thermal properties, making it suitable for use in advanced technologies such as solar cells, semiconductors, and optoelectronics.
Ag2Te is known for its semiconductor properties, particularly when doped with certain elements. It exhibits a direct bandgap, which allows for efficient absorption of light and conversion into electrical energy. This feature makes it an attractive material for photovoltaic devices, where it can be used as a transparent conducting layer or as a part of thin-film solar cells.
In the field of electronics, Ag2Te is employed in thermoelectric generators and coolers, converting temperature differences into electricity or vice versa. Its high Seebeck coefficient and low thermal conductivity make it an effective material for waste heat recovery and thermoelectric power generation.
Additionally, silver telluride is employed in the production of X-ray shielding materials due to its strong absorption capacity for X-rays. Its ability to block harmful radiation makes it a popular choice in medical imaging equipment and radiation protection applications.
In the jewelry industry, silver telluride is occasionally used in creating unique and decorative finishes, offering a distinct aesthetic to silver-based products. However, it’s worth noting that its brittleness and lower malleability compared to pure silver limit its widespread use in this context.
From a chemical standpoint, Ag2Te is relatively stable under normal conditions but can be sensitive to moisture and air, necessitating proper storage in sealed containers to maintain its properties. Its synthesis methods include direct reactions between silver and tellurium, precipitation from solutions, or through various chemical reduction processes.
In summary, Silver Telluride powder CAS 12002-99-2 is a high-purity compound with versatile applications in semiconductor devices, thermoelectric technology, radiation shielding, and even decorative finishes. Its unique properties, including its direct bandgap, Seebeck effect, and absorption characteristics, make it a valuable material in modern technology and engineering. However, its specific usage depends on the desired application, and proper handling is essential to preserve its performance.
