Overview of High Purity Nano 325 Mesh Bismuth Powder CAS 7440-69-9 Bi Micron 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 High Purity Nano 325 Mesh Bismuth Powder CAS 7440-69-9 Bi Micron 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 High Purity Nano 325 Mesh Bismuth Powder CAS 7440-69-9 Bi Micron Powder
Bismuth, with the chemical symbol Bi and atomic number 83, is a brittle, lustrous, and silvery-white metal that belongs to the pnictogen group in the periodic table. Its CAS number, 7440-69-9, is a unique identifier assigned by the Chemical Abstracts Service for this specific compound. High purity nano bismuth powder, specifically in the 325 mesh size range, is a versatile material with exceptional properties due to its nanoscale particle dimensions.
Nanoscale particles, like those in the 325 mesh format, have a diameter ranging from 45 to 75 micrometers, providing a large surface area to volume ratio. This feature enhances the reactivity and interaction of bismuth with other materials, making it useful in various applications. The 325 mesh grading ensures consistent particle size distribution, which is crucial for maintaining uniform performance in different processes.
Bismuth nano powder exhibits high purity, typically above 99%, meaning it contains minimal impurities, ensuring its reliability in demanding scientific and industrial applications. The purity level is essential for maintaining the integrity of the final product and minimizing unwanted side effects or reactions.
The unique physical properties of bismuth nano powder include low density (9.78 g/cm³), non-magnetic behavior, and excellent thermal stability up to approximately 930°C. It has a relatively low melting point (271.4°C) compared to many metals, which makes it useful for certain thermoelectric applications where temperature differences generate electricity.
In the field of medicine, bismuth nano particles have shown potential in targeted drug delivery systems, as their small size allows them to penetrate tissues more effectively. They can be used as antibacterial agents in bandages or as components in dental fillings due to their biocompatibility.
In electronics, bismuth is employed in superconducting alloys, where the nano-sized particles enhance conductivity at lower temperatures. This property is exploited in applications such as magnetic resonance imaging (MRI) machines and power transmission lines.
In cosmetics and personal care products, bismuth oxychloride nano powder is known for its anti-inflammatory and skin soothing properties, often found in sunscreens and makeup products.
In environmental remediation, bismuth can be utilized as an adsorbent for heavy metals, demonstrating its ability to bind and remove contaminants from water or soil.
Lastly, in the realm of catalysis, bismuth nanoparticles exhibit unique catalytic properties, making them suitable for applications in the petrochemical industry, where they can improve reaction rates and selectivity.
In summary, high purity nano 325 mesh bismuth powder is a versatile material with a wide range of applications due to its exceptional properties, including its nanoscale size, high purity, and unique physical and chemical characteristics.
