The present invention relates to maintaining the fundamental physical properties of a liquid alkali metal with dispersed nanoparticles which is such that nanoparticles are uniformly dispersed and mixed in a liquid alkali metal used in heat exchange, cooling and other applications, and suppressing the reaction of the liquid alkali metal with dispersed nanoparticles. Provided is a method of manufacturing a liquid alkali metal with dispersed nanoparticles by dispersing nanoparticles in a liquid alkali metal. In this method, the nanoparticles are made of a metal having a large atomic bonding due to a combination with the liquid alkali metal compared to the atomic bonding of atoms of the liquid alkali metal and a metal having a large amount of charge transfer is used in the nanoparticles. The liquid alkali metal is selected from sodium, lithium and sodium-potassium alloys, and the nanoparticles to be dispersed are made of transition metals, such as titanium, vanadium, chromium, iron, cobalt, nickel and copper.

Suppression or enhancement of various properties of a liquid fluid is aimed by improving uniform dispersion of nanoparticles by means of making a state in which no oxidized film exists on the surfaces of the nanoparticles to be dispersed in the liquid fluid. The location of the liquid fluid is confirmed with ease by enhancing the brightness of light emission of the fluid through uniform dispersion of the nanoparticles in the liquid fluid containing a material having a flame reaction. In this way, as to liquid fluids utilized in various industries, it is possible to offer a technology to desirably enhance or suppress a property desired to be enhanced and a property desired to be suppressed among various properties that its constituents have.
