Both carbon black and activated carbon are carbon, but due to the different arrangement of carbon atoms, although the chemical properties are the same, the physical properties are different. The application of carbon black and activated carbon is also very different. It can be said that carbon black and activated carbon are no longer a product.
The structural difference between carbon black and activated carbon
The structure is different. Carbon black belongs to amorphous carbon, which is tiny carbon particles and has very low reflectivity. It is the most commonly used black pigment.
Activated carbon has an incomplete graphite structure, which is black powder or block, granular, honeycomb amorphous carbon, and there are also regular crystalline carbons.
The difference between carbon black and activated carbon
Carbon black is generally used for reinforcement, coloring, conductivity, etc., and is a black pigment additive.
Due to its strong adsorption, carbon is widely used in production and life as an adsorbent.
The difference between the oxidation treatment of carbon black and activated carbon
Carbon black is generally not an oxidized carbon material.
Activated carbon is a carbon material that has been treated or activated by O2 or other chemical reagents.
The specific surface area difference between carbon black and activated carbon
Generally, the specific surface area of carbon black is larger than that of activated carbon.
Through the above comparison of the difference between carbon black and activated carbon, we found that carbon black and activated carbon are no longer a product, they just have the same chemical properties, and there are many other differences.
