Parameters of High Purity CAS 12034-77-4 Niobium Selenide NbSe2 Powder
Niobium selenide (NbSe2), a compound with the chemical formula NbSe2, is a fascinating material in the realm of inorganic chemistry and materials science. It boasts a high purity, which is a critical aspect for its numerous applications across various industries, particularly in electronics, superconductivity, and optoelectronics.
CAS number 12034-77-4 serves as a unique identifier for niobium selenide, ensuring consistency and traceability in the global marketplace. This alphanumeric code is assigned by the Chemical Abstracts Service (CAS) and acts as a universal reference point for the compound.
The powder form of NbSe2 is of particular interest due to its inherent properties. As a fine, powdery substance, it offers high surface area, enabling efficient contact with substrates during synthesis or device fabrication processes. The particle size and morphology can be tailored through controlled synthesis methods, such as chemical vapor deposition (CVD), hydrothermal synthesis, or mechanical grinding, to optimize performance in specific applications.
Niobium selenide is known for its layered structure, where niobium (Nb) atoms are sandwiched between selenium (Se) layers, forming a van der Waals bonded crystal lattice. This structure gives rise to interesting electronic properties, including a semiconducting nature at room temperature, which can be tuned to metallic behavior under certain conditions. This tunability makes NbSe2 an attractive material for potential use in electronic devices, like transistors and sensors.
One of the most intriguing aspects of NbSe2 is its potential for high-temperature superconductivity. When cooled below a critical temperature (typically around 9 Kelvin), the material exhibits zero electrical resistance, allowing for lossless current flow. This property holds great promise for developing next-generation energy-efficient technologies, such as power transmission lines and quantum computing.
Moreover, niobium selenide has shown promise in optoelectronic applications due to its ability to absorb and emit light in the visible and near-infrared regions. Its photoluminescence properties make it suitable for applications like light-emitting diodes (LEDs) and photodetectors.
In addition to these, NbSe2 has found applications in catalysis, where its surface chemistry can be modified to enhance its activity for various chemical reactions. It has also been explored in lithium-ion batteries as a cathode material, offering high capacity and stability.
However, it’s important to note that handling high purity NbSe2 requires strict precautions due to its reactivity with moisture and oxygen. Proper storage in an inert atmosphere and clean handling techniques are crucial to maintain its quality and integrity.
In summary, niobium selenide (CAS 12034-77-4) is a versatile material with exceptional properties, making it a sought-after compound in multiple scientific and industrial domains. Its high purity, layered structure, and tunable properties open up a wide range of possibilities for applications in electronics, superconductivity, optoelectronics, catalysis, and energy storage systems. As research continues to uncover more about this material, its importance in the modern technological landscape is likely to grow.
