We have long experience in handling and processing of nanoparticles/nanopowders, for example, mix and granulate different powders and binders for to achieve improved homogeneity and increased performance of the final product.
Freeze granulation gives the possibility to granulate nanoparticles/nanopowders achieving granules with high degree of homogeneity which are easily re-dispersed (if applicable) in a liquid or dis-integrated at a pressing operation. This is owing to the week inter-particle bonding compare to what is obtained in conventional drying. Consequently, the nanosized material properties will be preserved, i.e. nano will still be nano. Freeze-drying also prevents oxidation of metals or non-oxide materials as conventional drying do not, especially critical for nanopowders.
