Nanopowder Synthesis & Processing

As part of our nano-initiative, Ceramatec, Inc. has synthesized ceramic nanopowders using a nano-powder synthesis process that results in very high purity, high-quality, un-agglomerated, high surface area, nanocrystalline ceramic powders.

We have the capability to invent, develop and scale up proprietary technologies for producing nano-powders for targeted applications like infrared windows, catalysts, fuel cells, and even cosmetics.

Ceramatec looks forward to collaborating and expanding in the area of nanotechnology through research sub-contracts, business partnership, and R&D investments. New ideas and practical approaches are at the forefront of our efforts. Ceramatec may also entertain special custom orders for synthesizing novel nano-ceramic powders.

Powders with different properties for various targeted applications can be synthesized by varying:

  • Surface Area
  • Crystallite Size
  • Paricle Size
  • Purity
  • Dopant type & dopant concentrations (mixing & dispersion at nano-level)
  • Single phase or two phase mixtures (nano-phase mixtures)

NanoCeramic powders – single phase or two phase mixtures of Y2O3, CaO, TiO2, SnO2, Al2O3, ZrO2, ZrO2-x mol% Y2O3, Fe2O3, and ZnO – with a wide range of powder properties can be manufactured using our proprietary process.

Examples

Powder properties of Nanocrystalline Yttria (Y2O3) synthesized at Ceramatec:

  • Ultrafine powders: 35 nm mean particle diameter (90% under 40 nm)
  • High Purity: >99.986%
  • High surface area: ~100 m2/g
  • Monodisperse: Std dev. of ~20% in diameter
  • Unagglomerated
  • Phase Pure (fully cubic)
  • Good Sinterability
  • Unique Process & Low Cost (For large volume production)

Crystallite Size / Particle Size Data on Yttria Nanopowders synthesized inhouse:

  • Crystallite Diameter from XRD - 11nm
  • BET Surface Area - 111 m2/g
  • Crystallite Diameter (calculated from surface area, assuming spherical particles) - 10.8 nm
  • Crystallite Diameter measured from TEM - 10 to 20 nm
  • D50, Particle Diameter measured from powder particle size analysis - 30 nm

Chemical Purity: ICP-MS (60 element screen) data suggest powders are >99.986% pure with extremely low Si content.
