Abstract
When the solid solubility limit is
lowered by cooling the iron-carbon liquid,
the DPG precipitates on the liquid. It’s
different from Kish Graphite. The high
degree of graphitization graphite is produced
with the catalysts of iron and boron. In this
experiment, we produce the DPG graphite by
the variation content of boron in the ironcarbon
liquid. The DPG is characterized by
X-Ray Diffraction and Scanning Electric
Microscope. The X-Ray Diffraction patterns
are refined by Rietveld method to identity its
exact degree of graphitization. The high
degree of graphitization of the new produced
graphite is about 95% as good as the DPGCH
that produced before (about 96%). The
XRD peaks in the profile of fullerenes had
also been discovered on the low angle and
there are about 5~6% fullerenes in the DPG
graphite. We also observe the carbon tube in
the D0 from SEM.
