Description
Silicon Hexaboride (SiB₆) Nanopowder
Average Particle Size: 40 nm | Purity: 99% | Crystal Structure: Hexagonal | Color: Grey-Black
Product Overview
Silicon Hexaboride (SiB₆) Nanopowder is a high-performance ceramic nanomaterial known for its extreme hardness, chemical inertness, and high thermal stability. With a melting point of 2200 °C and exceptional resistance to oxidation and thermal shock, SiB₆ nanoparticles offer enhanced strength, wear resistance, and grinding efficiency, making them superior to traditional abrasives like boron carbide in certain applications.
Thanks to their nanoscale particle size (~40 nm) and uniform morphology, SiB₆ nanoparticles are widely used in abrasive engineering, refractory formulations, advanced ceramics, aerospace composites, and powder metallurgy.
