Oxidation of carbonaceous matter—II: X-ray diffraction and transmission electron microscopy

摘要: Abstract When oxidized under an air flow at various temperatures, carbonaceous materials show evolution of their elemental composition along a path which depends on initial ( O H ) atomic ratio (Part I). A molecular orientation is obtained during the subsequent carbonization process, extent decreases as sample increases. Correspondingly graphitizability progressively. Both and tend to zero when material tends reach “oxychar” C ∼- 0.5 ).
