Methods for the preparation of nanosized material particles
First Claim
1. A method for the production of transition metal, metal alloy, metal oxide or ceramic nanomaterial particles comprising the steps of:
- synthesizing nanomaterial particles in solutions of complex liquids from suitable precursors, which precursors are selected from the group consisting of suitable surfactants, alkoxides, and metal salts, by a suitable chemical reaction under mild conditions, wherein the water in the solution is nonfreezing water; and
preparing fine colloids dispersed in various polymer solutions.

Abstract
The present invention relates to a method for the production of particles of nano-materials being transition metals and alloys; metal oxides; and ceramic compositions having a small nanosize, i.e. about 1-6 nm. The method comprises a synthesis in the solutions of complex liquids from suitable precursors, which precursors are selected from suitable surfactants and alkoxides, by a suitable chemical reaction under mild conditions; and preparing from said materials fine colloids dispersed in various polymer solutions. The water in the solution is preferably non freezing water, the mild conditions are atmospheric pressure and a temperature range of room temperature to 70° C., and the reaction condition is selected among a hydrolysis, reduction and exchange process.
