Amorphous nanoparticles, production method and dispersion
Easy production of well-dispersed amorphous nanoparticles at low temperature
Summary
Liquid quenching method and atomization method are known as
conventional methods of producing amorphous particles. However, the
amorphous particle size obtained by these methods is relatively large and
it has been difficult to obtain nanometer order amorphous nanoparticles,
including amorphous tissue. Although chemical and arc plasma discharge
methods are known to produce metal nanoparticles, the application of
those methods are not easy due to the formation of secondary particles
and segregation. Furthermore, it is also difficult to obtain large quantities of
nanoparticles.
This invention is able to provide amorphous nanoparticles, its production
method with excellent dispersibility at relatively low temperatures, and
amorphous nanoparticle dispersions. This invention includes the process
of obtaining a dispersion with a solid-state metal comprising an alloy and a
reducing dispersant, and the process of irradiating the dispersion with
ultrasound in order to obtain amorphous nanoparticles containing an
amorphous structure from the solid-state metal.
Effect
・High dispersible amorphous nanoparticles easy production at low temperature Temperature
・The agglutination of the particles is avoided and their thermal properties is not changed even after a long period of time
Application
● “Nano-solder” which is a nano size solder
