ADSORPTION-STRUCTURAL CHARACTERISTICS OF CARBONACEOUS DIAMOND-CONTAINING MATERIALS PRODUCED BY DETONATION

A diamond-containing carbonaceous material produced by detonation is a complex composite of diamond, diamond-like, and nondiamond forms of c arbon. When this material is oxidized with nitric acid the specific su rface area and specific adsorption are extremely dependent on the degr ee of decomposition of the carbon and the maximum adsorption GAMMA(H+, OH-) = 6-8 mug-eq/m2 corresponds to minimum values of S(sp) = 180-200 m2/g . From such values for the ratio of the surface parameters we can conclude that this material contains diamond-like carbon structures t hat form the peripheral section of a diamond clast.
