How to choose the right graphite powder? Let's take a look:

The higher the finish of the graphite powder with a small particle size: For example, graphite powder can be used as a negative electrode material for the battery, and the size of the graphite powder particle size directly plays an important role in the finish of the entire production process, because the smaller the particle size, the higher the finish of the processed product. So is it that the smaller the particle size of the graphite powder selected, the better? Of course not, after the graphite powder particle size is small, the bending strength of the product will decrease, which will lead to cracks inside the electrode, and even breakage at high temperatures. Therefore, we will find that large-sized graphite electrodes are not produced with small particles of graphite.

The particle size will affect the expansion of the scale graphite powder: the expansion multiple of graphite is proportional to the particle size of the graphite. Expanded graphite has a rich pore-like structure, the smaller the particle size of graphite, the network pore structure of expanded graphite will also be reduced, the lower the coefficient of expansion, and vice versa, the larger it will be. Therefore, in the fields of sealing, fireproof coatings, etc., graphite with large particle size should be selected as a material. Now, the particle size of the graphite material is developing in a subtle direction, but it is not that the smaller the particle size, the better the graphite performance, find the right graphite for your own industry, and have a higher cost-effective application is the key problem.
