Abstract：The preparation technology of white carbon black (WCB) from water glass and simulative lime-kiln gas is studied systematically and experimentally by carbonization method, in which exhaust gas from production of calcium carbonate is utilized. The experiments are carried out by examining the influences of reaction temperature, reaction time, material ratio, carbon dioxide content on the yield of WCB and product characteristics (average particle diameter of WCB and rate of DBP absorption). The optimum experimental conditions have been gained as follows: reaction temperature 85~95℃, reaction time 2.5 h, volumetric ratio of water glass to water 1:6, and carbon dioxide content of simulative lime-kiln gas 40%. The present results would offer important reference for industrialisation of preparation technology of white carbon black as inorganic filling agent with fine capability and high compensation.
