thin film fabriion. Fig. 2.1 Different stages of non vacuum processing used for CZTS/Se thin film processing. 2.1.2.1 Ball milling: Ball milling is a simple and efficient technique which not only reduces the size but also induces chemical reaction. It allows a low temperature reaction and directly synthesizes the product [6].

A ball mill is a type of grinder used to grind and blend 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

Feb 3, 2012 The objective of milling is to reduce the particle size and blending of particles in new phases. The different type of ball milling can be used for synthesis of nanomaterials in which balls impact upon the powder charge[1]. The balls may roll down the surface of the chamber in a series of parallel layers or they
