Aggregated diamond nanorods, the densest and least compressible form of carbon

  • We report the synthesis of aggregated diamondnanorods (ADNRs) from fullerene C60C60 at 20(1) GPa and 2200  °C using a multianvil apparatus. Individual diamond nanoroads are of 5–20 nm in diameter and longer than 1μm1μm. The x-ray and measured density of ADNRs is ∼0.2%–0.4%∼0.2%–0.4% higher than that of usual diamond. The extremely high isothermal bulk modulusKT=491(3)GPaKT=491(3)GPa [compare to KT=442(4)GPaKT=442(4)GPa of diamond] was obtained by in situx-ray diffraction study. Thus, ADNRs is the densest among all carbonmaterials and it has the lowest so far experimentally determined compressibility.
