Which has a macro-scale synthetic diamond has been widely used

The synthesis of diamond static method, explosion and detonation shock method, these synthesis methods of different diamond particle levels, must be purified and used for  cutting tools  can be graded. Which has a macro-scale synthetic diamond has been widely used, and nano (micro) scale diamond applied research, after ten years of development, in the ultra-precision  abrasive wheels , abrasion coating, oil-modified polymer composite materials, computer chips and printed circuits, etc., has made remarkable achievements, and shows a very bright future.
