The impregnation of graphite bodies with coal tar pitch has been studied on a laboratory scale as a function of pore size distribution, impregnant and the impregnation variables of time, temperature and pressure. A mathematical description of the impregnation process in which the general form of Dar

β¦ Synopsis
The gas permeability of extruded graphite is extremely sensitive to the direction in which gas flow is measured. The technique of permeability measurement has been used to study the variation of pore structure of an extruded graphite and the data showed that a distinct directional pore pattern is present in this material. The factors which affect the pore structure of extruded graphites are discussed.

Gas permeability of a high-density isotropic graphite block was reduced by coating the carbonization of aromatic polyimide by using a solution of polyamic acid. Imidization at 400Β°C in nitrogen atmosphere after the solvent was vaporized out was essential for good adhesion with graphite substrate. By

The result also implies that the diffusion actively occurs up to about l-2 l.trn from the exterior, but gradually decreases through the diameter of fiber. It may be reasonable that the diffused phosphorus somewhat contributes to retarding possible reactions with oxygen by blocking many active sites
