Detonation Nanodiamond is ball-shaped with the particle diameter ranging from 2 to 15 nanometers and an average diameter of 7nm. It is hard, chemically constant, abrasion-resistant, super corrosion-resistant and high heat conductivity, refractory and highly conductive. It has big special surface ranging from 280 to 420 m2/g, high surface activity, rich surface functional group such as oxatyl, carbonyl, hydroxy group. It also has good biological compatibility and cold emission function. Those advantages make nanodiamond a important role to promote the competitive power of traditional industry...
