Physical Basis and Application Overview of Nanodiamonds
Diamond is the hardest substance on earth and the most valuable diamond material. Among all natural and synthetic materials, diamond has the highest hardness and thermal conductivity, the widest optical transmission range, the widest frequency response range, the highest refractive index, the best abrasion resistance, the best acoustic properties, the best resistance to radiation, and the best resistance to corrosion. It can be said that diamond is the most perfect functional material in the material world so far. Since diamond powder has potential application prospect in military and national economy, its preparation technology has been paid more and more attention.
