Products of Green Earth Aerogel Technologies
 

 

      Description:   Silicon based aerogels with chemical composition of Silicon Dioxide (SiO2)  of about 99.99% purity from rice husk ash. Hydrophilic but can be treated to be hydrophobic. Suitable for non water based filtration of liquids. Can be used as source of silicon metal or as material for Silicon diodes. Production process is carbon negative. Only small amount of carbon from the husk is liberated as CO2 the rest is intact in the rice plant.
   Density:    Average density of 0.15gm/cc - 0.33gm/cc gets more brittle at low density and breaks into powder.
     Appearance:    White to translucent foggy appearance

Thermal Conductivity:  

 0.017 W/mK (~R10/inch) (could be higher as it gets denser ). Ideal for use in high temperature insulation. Performance depends on conditions of use and is not guaranteed.

Amorphous Carbon Aerogels from Rice Husk and Rice Powder
 
   Description:    Amorphous Carbon aerogels from carbonated rice husk and rice powder (C) with about 99.00% purity. Can withstand water and does not break easily compared to silicon aerogels. Reacts with oxygen at 400 degree Celsius. Ideal for use as capacitor material. Production process is carbon negative. Only small amount of carbon from the husk is liberated as CO2 the rest is intact in the rice plant.
   Density:   Average density of 0.15gm/cc - 0.33gm/cc gets more brittle at low density and breaks into powder.
     Appearance:    Very dark Black and can block Infrared rays

Thermal Conductivity:  

 0.017 W/mK (~R10/inch) ideal for low temperature insulation eg. freezers and cryogenics. The Carbon aerogel has undistributed density which could affect its performance and cannot be guaranteed.
