Parameters of High Purity CAS 12034-77-4 Niobium Selenide NbSe2 Powder
Niobium Selenide (NbSe2), also known as niobium diselenide, is a compound with the chemical formula NbSe2 and a high purity form that is often sought after for its unique properties in various scientific and industrial applications. As a material with CAS number 12034-77-4, it stands out due to its distinct characteristics.
Niobium Selenide is an inorganic compound formed by the combination of niobium (Nb), a transition metal from the group 5 of the periodic table, and selenium (Se), a non-metal from group 16. It crystallizes in a layered structure, which gives it a lamellar or platelet-like morphology. This layered nature allows for excellent electrical conductivity and thermal stability, making it a promising material in electronic devices.
In terms of purity, high-purity NbSe2 typically has a minimum impurity level, ensuring that the material exhibits minimal contamination and impurities that could affect its performance. The purity level is crucial for applications where high reliability and consistent performance are essential, such as in superconducting devices, thin-film transistors, and optoelectronic components.
The powder form of NbSe2 is often prepared through various synthesis methods, including chemical vapor deposition (CVD), hydrothermal synthesis, or solid-state reactions. The resulting particles are generally uniform in size, with a narrow particle size distribution, which contributes to the overall homogeneity of the material. This property is beneficial for achieving optimal performance in devices where the surface area and grain boundaries play a significant role.
One of the most notable features of NbSe2 is its ability to exhibit superconductivity below a certain critical temperature. When cooled below a specific threshold, the material transitions into a zero-resistance state, allowing for efficient energy transmission without power loss. This makes it a valuable component in superconducting magnets, power cables, and quantum computing technologies.
Furthermore, NbSe2 possesses a strong spin-orbit coupling, which is vital for applications in spintronics and topological materials research. Spintronics explores the use of electron spin rather than just charge, leading to potential advancements in data storage and processing.
In addition to its electronic properties, NbSe2 has shown potential in catalysis, specifically as a support material for metal nanoparticles, enhancing their activity and selectivity in chemical reactions. Its large surface area and layered structure provide active sites for various chemical processes.
In summary, high-purity CAS 12034-77-4 niobium selenide (NbSe2) is a versatile material with exceptional properties, including superconductivity, spintronics capabilities, and potential catalytic applications. Its layered structure and high purity make it a sought-after compound in numerous scientific fields, driving innovation in electronics, energy, and materials science. As research continues to explore new applications and improve understanding of its properties, NbSe2 is poised to play a significant role in the future of technology.
