First of all, carbon black and white carbon black are completely different materials. It is only a common saying that it has evolved into such a reading only because of similar physical shapes.

Carbon black is called carbon black because it is an amorphous carbon. Light, loose and extremely fine black powder with a very large surface area. It is a product of carbonaceous materials (coal, natural gas, heavy oil, fuel oil, etc.) that are incompletely burned or decomposed by heat in the absence of air. It is called “soot” or “turpentine soot”.

Silica is a chemically derived silica powder. However, "white carbon black" is actually a wrong name. Because it has a reinforcing property similar to that of carbon black in rubber, it is white, so in order to distinguish it, some foreign countries call it White Carbon Black, that is, white carbon black
