Claims20
A method for producing a milled powder comprising the steps of providing a starting powder, imparting an electrostatic charge to said starting powder to form a charged powder, and milling said charged powder to produce a milled powder, wherein the step of imparting an electrostatic charge to said starting powder further comprises:
- (a) providing a charge generator and a milling fluid;
- and
- (b) flowing said milling fluid through said charge generator so that said milling fluid becomes electrostatically charged.
A method for producing a milled powder comprising the steps of providing a starting powder, imparting an electrostatic charge to said starting powder to form a charged powder, and milling said charged powder to produce a milled powder, wherein the step of imparting an electrostatic charge to said starting powder further comprises:
- (a) providing a charge generator;
- and
- (b) directly charging said starting powder.
