Desorption Kinetics at Heating of Detonation Nano-Diamond
The research work analyzes molecular structure of volatile compounds of detonation nano-diamond. It is established that water, hydrogen, nitrogen, methane, carbonic gas, sulfur dioxide are the basic volatile impurities. Concentration of volatile compounds essentially decreases during annealing. The mass of the sample can be decreased by 20%. Weight reduction is accompanied by endo- and exothermic effects.
Key words: detonation nano-diamond, impurity atoms, impurity concentration, impurity desorption, mass-spectroscopy of the desorption particles.
