Abstract
A method for preparing suspension of inorganic nanoparticles is described herein. The method includes mixing a dispersing medium () with a dispersant () and a metal oxide powder () to form a primary mixture (), the dispersant () being selected based on interaction energy of the dispersant () with respect to the dispersing medium () and the metal oxide powder (). The method further includes grinding the primary mixture () to obtain a suspension (), wherein at least the dispersant () is added to the primary mixture () during the grinding after predetermined time intervals.
