Experimental Research on the Preparation of White Carbon Black by Acid Treatment of Wollastonite

The authors expound the principle for the preparation of white carbon black by acid treatment wollastonite and investigated its technological flowsheet. The authors also point out the particle size of wollastonite, concentration of HCl solution, and time and temperature of the reaction have influences on the reaction degree of wollastonite and quality of white carbon black. The industrially standardized product has been produced in the optimum condition under which energy consumption and production cost relative low.
