S1MES  is our 1 micron  equiaxed silicon dry powder that is >98% free of oxygen/silicon oxides and carried in ethanol slurry .  $25/KG for lab and preproduction scale quantities.  Volume pricing availabile on 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 also facilated the avoidance of sialon formation. 

Price includes standard 5 day ground shipping anywhere within the US. Contact us for quotes for non US locations. 

Packing:  
 

S1MES 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 500 nano-meter silicon for improved performance.  S500NES 

Nano-silicon powders require special handling and cannot be shipped via air.   Please refer to the SDS for safety details.
