Today, we briefly introduce the relationship between the density of graphite products and carbon black.

We can add some carbon black to meet the demand of high mechanical strength for small size graphite products. Carbon black can not only greatly increase the mechanical strength of graphite products, but also increase the density of graphite products (filling the gap of particles).

However, for large size graphite products, practice has proved to be inappropriate. The reason is that carbon black will reduce the permeability of graphite products during calcination, which leads to easy cracking of graphite products.
