Graphite rods represent the band gap of graphite atoms. Generally speaking, it is the radius of graphite rods. Graphite rods have a regular hexahedral structure, that is, the band gap of each graphite rod is the same. The quality is small, the density is small.

First of all, there is no difference

It should be a graphite rod. The graphite rod is just a vivid metaphor that everyone has achieved together!

Because graphite rods do not need to consider the crystal interface, they are the lightest. Although the graphite rod is light, there are also cases where other substances crush it into nuclei. After considering these properties, the graphite rod can become a sphere with a hexahedral structure whose mass is much greater than the original mass.

Graphite rods have a large mass and no radius limitation, but the radius of graphite rods cannot be determined within a single crystal or among several crystals. Relative graphite rods are not much more accessible to fabricate than the original crystals. And because of this structure, the mass is multiplied.

Because they are all the same haha

There is no difference, the graphite rod is that you dig out the graphite and flatten it into a sphere

If you distinguish by weight, iron rods had such characteristics in the earliest days: iron rods and diamonds have similar physical properties, high density, and high hardness. However, the high-density graphite rods are too heavy and can only be used for industrial purposes, as a common repair method, so the original graphite rods are no longer used. In terms of physical properties alone, there is no difference between these two things, they are both very hard things. But later, people discovered the problem: Although the iron rod is heavy, it has a problem with the outer surface area, so it is easy to polish with a copper rod, and it does not need to reduce the volume, and the processing is simple, so the iron rod eventually became the main repair method for repairmen. Graphite rods are more convenient for repairing and cutting files.
