High temperature dynamic diffraction experiments on porous nano-diamond particle mixtures

This paper describes experiments to obtain dynamic x-ray diffraction data for porous nanodiamond (ND) mixtures. Two sample types were prepared to investigate different loading techniques, the first was a mixture of VitonTM polymer, nano-diamonds and controlled size glass microspheres, and the second was a hand packed loading of nano-diamonds in a cell. Our results suggest that the techniques can be used to: (1) determine reaction thresholds of polymers and (2) the combination of low porosity ND samples or mixtures and high velocity impacts of copper or Lithium Fluoride are able to produce melting in the nanodiamond. Because carbon has a high melting point, the technique likely can be used to obtain diffraction data to determine either reaction or melt thresholds for most materials.
