ABSTRACT:
Sononochemistry permits extremely rapid cooling to produce nanoscale particles. If magnetic, these particles are valuable for magnetic recording media, manufacture of permanent magnets, and other uses. In the present invention, we sonicate neat metal carbonyl to produce particles which we separate, generally magnetically, from the metal carbonyl, thereby making the production process as simple as possible and continuous.
