energy ball mill technique. The powders obtained after 75 h of ball milling had sphericallike morphology with an average particle size diameter of m. The powders were composed of nanoscaled grains of less than 10 nm in diameter. These obtained powders were consolidated at 1500 oC with a pressure of 30 MPa into fulldense bulk samples, using spark plasma sintering (SPS)

Ball milling is a typical technique for preparation of powder particles in the metallurgical and ceramic industries. For metallic systems, usually microsize particles are obtained even for an extended milling time because the crushed fine particles can be cold welded again during ball milling [9]. Surfactant addition can improve the milling efficiency so that smaller particles down to

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about
