PLANETARY BALL MILL METHOD AND SOLVOTHERMAL METHOD

摘要

The present invention relates to a method of manufacturing a nano crystal by using a ball milling and a solvothermal method at the same time and installing a heater in a planetary ball mill apparatus to increase a pressure inside a vessel, and the planetary ball mill apparatus including: a base; a heating bath installed onto the base and having a space therein, and provided therein with a heating mean; a rotating plate installed on the base inside the heating bath; and a milling vessel installed on the rotating plate to rotate according to a rotation of the rotating plate, having a space therein and being able to rotate with respect to the rotating plate, in which a raw sample, a milling ball, and a solvent are loaded in the milling vessel. Accordingly, the present invention may control pressure by controlling temperature and may manufacture a nano crystal without a post heat treatment.
