Nanocomposites by rapid solidifcation route

Abstract

Nanometric aggregates of solids can be classified into two types, nanograined or nanophased materials and nanocomposites. In the present paper after a brief review including the relation between size and boundary fraction, the basic principles that can be utilized to synthesize these materials from liquid route has been discussed. We shall present examples to show that with proper choice of systems and conditions it is possible to obtain nanocomposites in systems showing clustering tendencies in liquid as well as the systems exhibiting ordering tendencies leading to compound formation. © 1992 the Indian Academy of Sciences.
