Abstract
The invention discloses a method for forming particle form polynary nano compound, which comprises the steps of (S1) mixing at least two materials, selected from a pre-determined group, to contact it with a aliphatic amine to form a mixture; (S2) inputting a noble gas to the housing that the mixture disposed; (S3) heating the mixture to a first temperature and maintain at the first temperature for a first period; (S4) heating the mixture to the second temperature by a pre-determined heating rate and maintain at the second temperature for a second period; (S5) precipitating the particle form polynary nano compound from the mixture by a pre-determined way.
