Polycrystalline diamond and manufacturing method thereof, scribe tool, scribing wheel, dresser, rotating tool, orifice for water jet, wiredrawing die, cutting tool, and electron emission source
Nano polycrystalline diamond is composed of carbon, an element of different type which is an element other than carbon and is added to be dispersed in carbon at an atomic level, and an inevitable impurity. The polycrystalline diamond has a crystal grain size not greater than 500 nm. The polycrystalline diamond can be fabricated by subjecting graphite in which the element of different type which is an element other than carbon has been added to be dispersed in carbon at an atomic level to heat treatment within high-pressure press equipment.
