The pyrocarbon, gas phase densification of the catalytic carbon formations (CCFs), obtained on iron

Investigations on gas-phase densification of CCFs, obtained on iron, using the radially driven pyrolysis zone and, at the same time, the temperature rise in the pyrolysis zone with the speed of the 1.25 °C/h, were carried out. CCFs, bonded with pyrocarbon (CCFBPyC), not refined from iron, without defects, with density and PyC content corresponding to the material: graphite bonded with pyrocarbon (GBPyC), which include 90 wt.% of PyC (GBPyC-90), were obtained. The necessity of applying the special technological methods in the process of gas-phase densification of CCFs, was confirmed. (author)
