The polishing efficiency of nano-diamond polishing solution is 4 times times higher than that of nano-silica sol, and the surface roughness is significantly reduced. With its silicon carbide crystals, sapphire, hard disk head, glass-ceramics and other difficult hard-brittle materials polishing, in recent years, the development of extremely fast.
The surface roughness of sic crystals can reach 0.1~0.3 nanometer after polishing.
This allows the computer's hard disk surface to be ultra-smooth to meet the current storage density of up to 15.5gb/Square centimeters of the highest requirements. Broad prospect of application of nanometer diamond.
