The transition diamond-graphite will never be obtained within even the age of the universe. But the transition from amorphous silica to ordered silica (quartz) has a much lower activation energy. This transition ... WebTo analyze the data on a small-angle scattering of neutrons and X-rays in powders of diamond nanoparticles, we have developed a model of discrete-size diamond nanospheres. Our results show that fluorination does not destroy either the crystalline cores of nanoparticles or their clustering in the scale range of 0.6–200 nm.
