Summary of Cercanam® Properties

  • Ultra-high surface area attainable in a monolithic ceramic part (as high as 100 m2/g)
  • Retains its high surface area after exposure at temperatures as high as 1000°C
  • Chemically stable at temperatures as high as 1500°C in air, H2, CO2, and syngas
  • Excellent thermal cycling and thermal shock resistance (from 800°C to room temp)
  • Offers low cost, one step processing
  • Can achieve near net shapes for complex geometries using wet casting or dry powder pressing, with near zero shrinkage after low-temp firing (200°- 800°C)
  • Excellent for micro-features and micro-channel applications, and high tolerance fabrication
  • Excellent potential for low-temperature (< 150-200°C) curable ceramic coatings and monolithic parts>
  • Moisture resistant and stable in boiling salt water after firing to 800°C

Cercanam® is expected to be an ideal material for diesel particulate filters (DPFs) for automobiles and diesel engines. It has very high strength, is lightweight, has excellent thermal shock, and is stable in harsh operating environments. Furthermore, its porosity can be easily tailored between 0.2 micron to 10 micron to give the desired pore size distribution for exhaust gas filtration.

The porosity is inherently present in the ceramic and therefore will not require a second wash coat for catalyst loading. In short, Cercanam® will serve both as a filtration membrane and as a substrate for catalyst.

We are currently seeking industrial partners to further this concept and conduct prototype testing.
