Abstract

A neutron diffraction study of the effect metal additives have on phase transformations at high temperatures and pressures in C₆₀ fullerene in the amorphous state and in the form of a face-centered cubic structure. It is found that introducing metals into crystalline C₆₀ fullerene considerably raises the temperature of its transformation into disoriented graphite. No such effect is observed in amorphous fullerene, since that of metal additives is compensated for by a reduction in the stability of fullerene due to amorphization produced by preliminary mechanical activation.

C 60富勒烯与铁和铝在高压和高温下的相变

抽象

的中子衍射研究吨他效果金属添加剂在高温和高压下用C对相变₆₀在非结晶状态和富勒烯中的面心立方结构的形式。已经发现，将金属引入结晶的C ₆₀富勒烯中会大大提高其转变为定向石墨的温度。在无定形富勒烯中没有观察到这样的效果，因为由于由初步机械活化产生的非晶化，富勒烯的稳定性降低而补偿了金属添加剂的效果。
