Silicon Hexaboride (SiB6) Nanopowder,  APS: 40nm, Purity: 99%

Performance characteristics
Nano silicon hexaboride powder is prepared by high-frequency plasma gas phase synthesis. It is a gray-black powder with a relative density of 3.0g/cm3 and a melting point of 2200°C. It is insoluble in water, resistant to oxidation, thermal shock, and chemical attack. It has high strength and stability especially under thermal shock, and the grinding efficiency is higher than that of boron carbide.

Manufacturing Method



1. It can be used as various standard abrasives and grinding cemented carbides;
2. It is also used as engineering ceramic materials, sandblasting nozzles, blades of gas engines and other special-shaped sintered parts and seals;
3. Used as an anti-oxidant for refractory materials;
4. Add in powder metallurgy and cemented carbide to improve strength, hardness, and heat resistance;
5. Used in aerospace carbon-carbon composite materials to improve the ablation resistance and high temperature strength of composite materials.

Packaging and storage
This product is packaged in an inert gas plastic bag, sealed and stored in a dry, cool environment. It should not be exposed to the air to prevent oxidation and agglomeration due to moisture, which will affect the dispersion performance and use effect; the number of packages can be provided according to customer requirements and packed.
