Abstract

Carbon blacks were oxidized by gaseous and wet oxidation techniques. Graphite was oxidized by potassium chlorate dissolved in mixed nitric and sulphuric acids. The resulting oxidized carbon blacks contain 5 to 20% oxygen, 1% or higher hydrogen, and the rest carbon. The oxidized graphite was heated to 200°C at which temperature it explosively forms a material that is very similar to carbon black. The exploded material contains 15% oxygen and the rest carbon. The X-ray work attempts to present a picture of the structure of these materials in terms of per cent disorganized matter, size of crystallites, distribution of thickness of crystallites, and the interplanar distance, according to the methods of Rosalind Franklin and of L. E. Alexander and E. C. Sommer.
