S500NMES is our 500 nano-meter equiaxed silicon dry powder that is >98% free of oxygen/silicon oxides and carried in ethanol slurry. Priced at $145/kg for lab/preproduction scale orders. Volume pricing upon request.
Designed for ceramics and chemical processing including but not limited to SiC, SiN ceramics, alumiinum alloys and chemical production of silanes & silicones.
SiC and SiN ceramics suppliers use our nano-sized materials to increase fracture toughness ( K1C) & reliability (Weibull Slope). Smaller sizes minimize the thermal mechanical failures associated with the mismatch of the coefficient of thermal expansion between the silicon core and SiN/SiC surface layers.
Smaller sizes helps avoid sialon formation.
Price includes standard 5 day ground shipping anywhere within the US. Contact us for quotes for non US locations.
Packing:
S500NES is delivered in sealed metal container containing 1.5 KG of metalurgical grade silicon in ethanol slurry. 65% solids loading, silicon content of 1KG on a dry weight basis.
Also available in 1 micron silicon in ethanol slurry.
Nano-silicon powders require special handling and cannot be shipped via air. Please refer to the SDS for safety details
