Abstract
A continuous method of manufacturing a liquid dispersion containing submicron metal or metal compound particles inside a liquid bath. A metal-containing fluid with carrier gas mixture is bubbled through the liquid bath and predetermined conditions in the bath cause the fluid to decompose to form the submicron sized metal or metal compound particles in the liquid.

A method of manufacturing a liquid dispersion that includes about 0.1 micron sized pure discrete metal-containing particles, the method comprising the steps of:
- providing a bath of a selected liquid in a vessel;
- mixing at least one metal-containing fluid with a carrier gas to form a metal-containing fluid mixture, the metal-containing fluid being capable of decomposing under predetermined conditions in the selected liquid to form pure discrete metal-containing particles;
- bubbling the metal-containing fluid mixture through the selected liquid in the bath;
- and
- establishing the predetermined conditions in the bath to cause at least some of the metal-containing fluid to decompose within the selected liquid in the bath to form the pure discrete metal-containing particles dispersed in the selected liquid.
A method for producing a liquid dispersion containing pure discrete metal particles of about 0.1 microns in size, the method comprising:
- providing a liquid bath in a vessel;
- mixing a metal-carbonyl gas with an inert carrier gas to form a metal-carbonyl gas mixture;
- introducing the metal-carbonyl gas mixture into the liquid bath;
- bubbling the metal-carbonyl gas mixture through the liquid bath;
- causing at least a portion of the metal-carbonyl gas to decompose within the liquid bath to form pure discrete metal particles of about 0.1 microns in size, and remain therein;
- and
- forming the liquid dispersion of the pure discrete metal particles in the liquid bath with a predetermined viscosity.
