THE FINE MICROSTRUCTURE OF PYROLYTIC GRAPHITE AS INFLUENCED BY BORON

Abstract

A study of the fine microstructure of boronated pyrolytic graphite was made utilizing optical and X-ray diffraction techniques. The influence of boron content on the laminar structure, the lattice parameter, the lattice strain, the particle size, and the flexural strength of pyrolytic graphite were studied. Significant changes in the behavior of all investigated parameters were observed in the 0.50 to 0.75 percent boron range. A mechanism relating these changes to the appearance of B4C deposit is hypothesized. (Author)
