Abstract:In the fourth chapter we have studied the effects of experimental parameters on size distribution of sonochemically generated Fe colloids. It has been found that changing temperature, precursor concentration, stabilizer amount, frequency, and sparging gas has no noticeable effect on the size distribution of Fe colloids, which remain in the 3--12 nm range. We have concluded that the size distribution does not change significantly because small Fe particles (∼0.4 nm with MP ≈ 350 K) melt together and coalesce to form larger (3--12 nm) particles, at which point the melting temperature is high enough that makes further coalescence unlikely.
