Abstract
A process for producing nano size powders comprising the steps of mixing an aqueous continuous phase comprising at least one metal cation salt with a hydrophilic organic polymeric disperse phase, forming a metal cation salt/polymer gel, and heat treating the gel at a temperature sufficient to drive off water and organics within the gel, leaving as a residue a nanometer particle-size powder.
Claims6
A process for producing nanosize powders comprising the steps of:
- mixing an aqueous continuous phase comprising at least one metal cation salt with a hydropolymeric organic polymeric disperse phase, forming a metal cation salt/polymer gel;
- and
- heat treating said gel at a temperature sufficient to drive off water and organics within said gel, leaving as a residue a nanometer size powder.
