Precipitation method white carbon black is another common white carbon black product, with a relatively simple production process and low cost. However, compared with gas-phase white carbon black, precipitation white carbon black has significant differences in performance and application fields.

Firstly, in terms of purity, precipitated white carbon black contains a significant amount of impurity ions, such as acid ions, alkaline ions, and alkaline earth metal ions, which may affect its application in certain high-end fields. However, gas-phase white carbon black only contains trace amounts of chloride ions and metal oxide impurities, with higher purity.


Secondly, in terms of particle morphology and specific surface area, the particle morphology and specific surface area of precipitated white carbon black are relatively poor. Its particles often exhibit irregular shapes and have a smaller specific surface area, which makes its performance in reinforcement, thickening, and other aspects inferior to that of gas-phase white carbon black.


In addition, gas-phase white carbon black also has excellent dispersibility and rheological adjustment ability, which can be uniformly dispersed in various systems and significantly improve the rheological properties of the system. However, the performance of precipitated white carbon black in this regard is relatively weak.
