Highenergy ball milling technique was successfully applied to calcinated lead zirconate titanate (PZT 60/40) powders. After 20 h of ball milling, large PZT particles were completely broken down, reducing its initial size in three orders of magnitude. Experimental results show a huge sinterability enhancement of the PZT powders by using this technique, achieving its maximum .

Abstract. The stability of the quasicrystalline phase present in ascast Al 65 Cu 20 Fe 15, Al 65 Cu 20 Co 15 and Al 72 Pd Mn alloys during high energy ball milling and on subsequent annealing has been studied. The synthesis and stability of the quasicrystalline phase prepared by mechanical alloying of Al 65 Cu 20 Fe 15, Al 70 Cu 20 Fe 10 and Al 65 Cu 20 Co 15 alloys .

Milling reduced particle size, enhanced amorphism, and increased the release of structural ions from the rocks, with the effects due to dry milling being greater than for wet milling. The optimum milling times which produced maximum amounts of exchangeable ions (Na, K, Ca, and Mg) were 30 90 min, depending on rock type.

Ball milling was combined with enzymatic pretreatment in order to decrease the energy consumption and to obtain high quality and homogeneity of the CNF. The process conditions, dispersity, morphology, degree of polymerization, and crystal structures of the resulting two kinds of CNF obtained were compared and discussed.

· A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

· The MDSC results show that high energy ball milling is capable of forcing the mixing of TD and SL at a molecular level, providing a homogeneous amorphous solid solution. The glass transition temperatures (Tg), determined for the comilled formulations, range from 79°C to 139°C and they are higher than Tg of pure SL (ca. 70°C) and lower than Tg of pure .

Planetary Mills are ideally suited for fine grinding of hard, mediumhard, soft, brittle, tough and moist materials. The comminution of the material to be ground takes place primarily through the highenergy impact of grinding balls in rotating grinding bowls. The grinding can be performed dry, in suspension or in inert gas.

A high energy ball milling (HEBM) technique has successfully been used to synthesis nanocrystalline ferroelectrics and other alloys [3, 4]. Though nanocrystalline ceramics can be synthesised by a range of different physical, chemical, and mechanical methods, HEBM offers several advantages over the other methods [ 5 – 7 ].
