Description
Silicon Carbide (SiC) Nanopowder / Nanoparticles – Beta Phase (99.5+%, <70 nm)
Silicon Carbide (SiC) nanoparticles, in the Beta (cubic) phase, are advanced ceramic nanomaterials known for their exceptional hardness, high thermal conductivity, and outstanding chemical stability. With a purity of 99.5+%, particle size of <70 nm, and a specific surface area of 20–55 m²/g, these grayish-white nanoparticles are manufactured via the Chemical Vapor Deposition (CVD) method, ensuring excellent quality and consistency.
Due to their high strength, wear resistance, and superior heat tolerance, SiC nanoparticles are widely applied in ceramics, refractories, composites, polishing, and high-temperature engineering applications. Their zeta potential of -27.5 mV also indicates good dispersion stability in colloidal systems, making them suitable for both research and industrial-scale uses.
