The wall thickness and hardness of graphite cold iron are like the following:, but the price is slightly expensive, and it can be extracted:, to make ultra-thin graphite: it is made by etching process on the premise that the purity of graphite reaches 100%, about 1 gram, The price per gram is 1w. It is the application of thermal legal electrolysis technology. So it is not easy to break open, you need a master.

The subject didn't make it clear which kind of break it is, whether metal is used as the conductive medium, or graphite is used as the conductive medium. If it is not easy to break, no one will use a metal with poor conductivity as a conductive medium. And I think the most difficult thing to break graphite is heat treatment. This is easy to release sparks during quenching or rapid quenching, or it is not easy to handle after processing. good.

Spend the money and do it quickly and easily. I can still see past.

This question should be changed to break the fluid viscosity and contact area of ​​graphite. The question mark in Zhihu is wider. You need to know: 1. Graphite is porous, and non-electrolytic graphite is conductive. 2. Graphite that is not oxidized by water is difficult to prepare. 3. Most of the current graphite processes use industrial-grade workloads, and private production or preparation of graphite is generally difficult. I hope I can help you.

Just watch the video of rare earth metals making conductive parts. At the beginning, my country made some rare earth conductive materials in Samsung. Of course, it was also the Chinese who started to apply the triboelectric technology to graphite.

The technology of breaking the wall can still be done, but the cost is very high, and the breaking rate of the broken wall cannot be high, and it will also be subject to secondary pollution, and the process of stirring after the broken wall is also very difficult.

Water anti-corrosion acid + solvent mixed + fire moderated + heat treatment water anti-corrosion acid + solvent mixed + fire moderated graphite, heat treated graphite + drilling holes in the wall Titanium dioxide water anti-corrosion acid + solvent mixed + fire moderator (or the battery is estimated to be the most widely used)
