taken below 42Β°K using a specimen of pyrolytic graphite heat-treated at 3250Β°K. In conjunction with zero-field resistivity and magnetoresistance data it will be shown that the "usual" Lorenz number provides an adequate description of the magnetothermal behavior of graphite. At saturation, measuremen

The electrical resistivity along 500 A thick carbon films has been measured from l-2 to 1100Β°K. The electrical resistivity measurements at high temperature indicate a change in the structure of the film beginning at about 670Β°K. In the theory of noncrystalline solids by Mott, the temperature depende
A medium and a high volatile matter (VM) anthracite and a medium and low VM carbon black have been exposed to chlorine gas, at one atmosphere pressure, at temperatures between 200-1400Β°C. For the high VM anthracite, chlorine fixation occurred at low heat treatment temperatures (HTT) primarily by sub
## Abstract The electrical resistivity of highβdensity polyethylene (HDPE) loaded with carbon black (CB) blends was evaluated as a function of the blending time and the melt index of HDPE. The relationship between the positive temperature coefficient effect and the room temperature volume resistivi
