description	Disclosed herein are methods and apparatus for producing nanometer scale particles utilizing an electrosterically stabilized slurry in a media mill. A method for producing nanometer scale particles includes adding to a media mill a feed substrate suspension. The feed substrate suspension includes a liquid carrier medium and feed substrate particles. The method further includes adding to the feed substrate suspension in the media mill an electrosteric dispersant. The electrosteric dispersant includes a polyelectrolyte. Still further, the method includes operating the media mill for a period of time to comminute the feed substrate particles, thereby forming nanometer scale particles having a (D90) particle size of less than about one micron, and recirculating for further grinding the nanometer scale particles from the media mill.
