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
