Abstract:

White carbon black is an additive widely used in such industries as rubber , tire , shoe , toothpaste , and feed making. Fluosilicic acid is a byproduct from the process of phosphoric acid production , which can be adopted as a raw material to prepare white carbon black with fairly good social and economic benefits. This paper summarizes the traditional preparation methods of white carbon black , and introduces technologies to prepare it from fluorosilicic acid by-produced in phosphate fertilizer production as well as their research progresses.

Keywords: fluosilicic acid / white carbon black / phosphoric acid
