◆Applications Tantalum carbide powder is primarily used as an additive for P-type cutting tools and cermets, as well as a particle growth inhibitor for sintering WC/Co cemented carbide. Additionally, cutting tools made from tantalum carbide can withstand high temperatures of 3800°C, and their hardness is comparable to that of high-grade diamonds, making tantalum carbide powder an important metal cermet material. As a grain refinement agent for tungsten-based alloys, it can significantly enhance the performance of the alloy, with a content of 0.5 to 5% in tungsten carbide-based cemented carbides. ◆Chemical Properties Molar Mass: 192.959 g/mol Appearance: Brown powder Density: 13.9 g/cm³ Melting Point: 3,880°C Boiling Point: 5,500°C Solubility in Water: Insoluble Crystal Structure: Cubic

"Si-P-015" is a silicon powder for the negative electrode of lithium-ion batteries, which is produced by washing, drying, crushing, and classifying Si sludge discharged from the silicon wafer cutting process. Since it is a cutting product of high-purity silicon wafers, the impurity concentration is originally extremely low. Although there is some contamination from metal impurities during the cutting process, the Si purity level is above 4N (excluding C/O). In a dried state, it achieves a particle diameter of D50=0.584μm, but because the crystals are stacked in a flaky shape, additional grinding using a wet ball mill or similar can achieve grinding down to the 0.1μm (100nm) level in a short time. 【Features】 ■ Cutting product of high-purity silicon wafers ■ Si purity level is above 4N (excluding C/O) ■ Achieves a particle diameter of D50=0.584μm in a dried state ■ Particle shape is flaky, with side dimensions of 100-200nm ■ Can be ground down to the 100nm level in a short time using a wet ball mill or similar *For more details, please refer to the PDF document or feel free to contact us.
