GRISH Nano-graphite

GRISH Nano-graphite is synthesized by the detonation of high power explosive mixing with graphite which is put into a chamber. During the process of detonation, high temperature and pressure can be caused. Under this condition, large amount of dissociative carbon atom integrate into nano-sized graphite.

Features:
● Small and homogeneous particle dimension
● High specific surface area , porous structure
● High thermal-stability and good performance of electriconduction and heatconduction
● Good performance of lubrication, anti-corrosion and thermal conductivity

Applications:
● For the feature of small and homogeneous particle dimension, can be used as nano-scaled compound-material or compound-paint additive.
● For the feature of high-purity and high specific surface area make it better to be hydrogen storage material than other materials.
● For the feature of high thermal-stability、electric/anti-corrosion performance and thermal-conduction features make it to be good electric and thermal conductive material.
● Additive to lubricant can diminish the friction coefficient and improve the ability of antifriction, resistance to ultimate-pressure and resistance to high temperature.
