An Investigation on Degree of Graphitization by Hall

In this study, physical properties of Graphite samples were measured by Hall Effect. Samples were taken to heat treatment as respect to different constituent of materials, after measuring by Hall Effect,ia,va,vH,IH then estimate by equation specific resistivity, number charge carriers, coefficient hall electron mobility. Electrical conductivity generalized directly proportional and linear with thermal conductivity more over from these electrical properties can be determine heat treatment temperature and degree graphitization.
