Ultrafine Graphites (UFG) prepared by explosive detonation in the water protective medium was studied. The advantages of the technology using water as protective medium are convenient and safe and low cost technology. Moreover,UFGs have high purity and concentrate granule. UFGs obtained from TNT,RDX and graphite have the medium size of 9.3 nm and the surface area of 1116.2 m²·g^-1.
