在2.6-3 GPa的非流体静压和700 °C的温度下，从纯C60富勒烯及其与铝的混合物中获得了非常坚硬和导电的碳。材料的硬度大于4000 kg/mm 2。它的电导率约为100 Ω−1 cm−1，在4.2-300 K范围内对温度的依赖性很弱。X射线衍射和拉曼测量显示在转化的材料中缺乏长程晶序。
A very hard and conducting form of carbon has been obtained from pure C60 fullerenes, as well as its mixture with aluminium at nonhydrostatic pressures of 2.6–3 GPa and a temperature of 700 °C. The hardness of the material is more than 4000 kg/mm2. Its electrical conductivity is about 100 Ω−1 cm−1 and is weakly dependent on temperature in the range 4.2–300 K. X‐ray diffraction and Raman measurements show lack of the long‐range crystalline order in the transformed material.
