摘要：

The grinding characteristics of natural graphite are discussed and a new graphite grinding method is proposed for obtaining fine particles. Natural graphite was well ground in dry air after vacuum drying at 10-3 Torr and 80°C and its 50% diameter of cumulative underside of products ground for 12 h was approximately 1.4 μm. The new grinding method was performed in dry air after treatments designed to increase the distance between layers and weaken the bonding strength by use of an intercalation reaction. Bromine gas was used as an intercalate and bromine graphite intercalation compounds were exfoliated by vacuum heating. The product size distribution for the exfoliated bromine graphite ground in dry air after vacuum drying was slightly different from that of ground natural graphite. © 1990.
