Abstract
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.
