Abstract

This research aims at studying the effect of temperature and calcination duration on characteristic of precipitated calcium carbonate (PCC). Limestone was converted in to PCC by using recarbonation method through calcinations, hydration and carbonation processes. Spesifically, calcination temperature had something to do with duration of lime stone to drive off CO2. Based on the analysis of physical properties, the size of particle PCC resulted on temperature 1100 0C with the surface area 30,96 μm2/g was smaller than one on 800 0C, 900 0C, 1000 0C And the percentage of its optical properties namely brithness was 94,9% and whiteness was 91,1 %. The XRF analysis showed that PCC had high purity level with CaO content 56 %. Then the XRD analysis showed that the PCC crystal was in the form of calcite.
