Abstract

A method of making ultrafine materials including metals, ceramics, and diamonds is disclosed. The general steps for producing these materials include: introducing at least one precursor material having a high absorption coefficient into a reaction sytem (12); providing at least one energy source (16) to rapidly dissociate and ionize said precursor material so as to produce an ultrafine material; and cooling (18) the ultrafine materials to prevent agglomeration.
