WebDec 9, 2016 · The obtained aragonite-precipitated calcium carbonate (PCC) is characterized by XRD and SEM, which is used to assess the morphology and particle size. Using the proposed process, oyster shell waste powder was calcined at 1,000 °C for 2 h, after which the calcined shell powder was dissolved in water for hydration. WebThe thermal decomposition process of the periwinkle shell sampleis presented in Figure 1. It is seen that the initial stage of mass-loss occurred in the range of 200 - 650 °C.This could be due to the vapourisation of moisturefrom the periwinkle shell sample.Also, it is seen that the heating rates of 10, 20 and 30
