Abstract
A process for producing a mixture of particulates using compressed gas and sonication. The process is particularly useful to mix reactive particulates, such as thermites.
Claims140
A process for producing a mixture of particulates comprising:
- forming a first dispersion comprising a first particulate material dispersed in compressed gas under agitation conditions effective to produce substantially no agglomeration, said agitation conditions comprising sonication and a temperature and a pressure effective to maintain at least a portion of said compressed gas in liquid phase;
- forming a second dispersion comprising a second particulate material dispersed in compressed gas under said agitation conditions, wherein said first particulate material and said second particulate material comprise reactive particulates;
- feeding said first dispersion and said second dispersion to a mixing zone under mixing conditions effective to produce a mixed dispersion comprising said first particulate material and said second particulate material;
- and
- separating said compressed gas from said mixed dispersion under collection conditions effective to collect said mixture comprising said first particulate material and said second particulate material.

A process for producing a mixture comprising superthermites comprising:
- forming a first dispersion comprising a first reactive particulate of the superthermite dispersed in compressed gas under agitation conditions effective to produce substantially no agglomeration, said agitation conditions comprising sonication and a temperature and pressure effective to maintain at least a portion of said compressed gas in liquid phase;
- forming a second dispersion comprising a second reactive particulate of the superthermite dispersed in compressed gas under said agitation conditions;
- feeding said first dispersion and said second dispersion to a mixing zone under mixing conditions effective to produce a mixed dispersion comprising said first reactive particulate of the superthermite and said second reactive particulate of the superthermite and to prevent redox reactions between said first reactive particulate of the superthermite and said second reactive particulate of the superthermite;
- and
- separating said compressed gas from said mixed dispersion under collection conditions effective to collect said mixture comprising said first reactive particulate of the superthermite and said second reactive particulate of the superthermite.

A process for producing a mixture comprising nanoaluminum and molybdenum oxide comprising:
- forming a first dispersion comprising nanoaluminum dispersed in compressed carbon dioxide under agitation conditions effective to produce substantially no agglomeration, said agitation conditions comprising sonication and a temperature and pressure effective to maintain at least a portion of said compressed carbon dioxide in liquid phase;
- forming a second dispersion comprising molybdenum oxide dispersed in compressed carbon dioxide under said agitation conditions;
- feeding said first dispersion and said second dispersion to a mixing zone under mixing conditions effective to produce a mixed dispersion comprising said nanoaluminum and said molybdenum oxide and to prevent redox reactions between said nanoaluminum and said molybdenum oxide;
- and
- separating said compressed carbon dioxide from said mixed dispersion under collection conditions effective to collect said mixture comprising said nanoaluminum and said molybdenum oxide.
