Abstract

Calcium oxide (CaO) is usually produced via thermal decomposition of limestone's obtained through mining and quarrying. However, this study manages to exploit the vast availability of natural calcium sources (Anadara granosa) or locally known as cockle shell in Malaysia. The efficiency of the calcinations process that transforms calcium carbonate (CaCO3) to calcium oxide (CaO) was often depended on the variable involved. Therefore, we wish to demonstrate the effects of experimental variables (calcinations temperature, heating rates and particle sizes) on calcinations of CaCO3 via thermos-gravimetric analyzer (TGA). Analysis of XRF, XRD and SEM were also conducted on the CaO produced after calcinations.
