METHODS OF PREPARING CARBON WITH A LOW PERMEABILITY

Patent ·
OSTI ID:4058404
Pieces of lndustrial carbon, notably moderator carbon, are evacuated and then impregnated under pressure with a sugar solution (d = 1.4 g/ml) or with molten sugar. The impregnant is carbonized at 175 to 300 deg C under a N/sub 2/ or He pressure of about 84 kg/cm/sup 2/ (dyne/cm/sup 2/). One or more of these treatments reduce the permeability 50- to 1000-fold.
