Abstract

The objective of this study is to produce β-wollastonite from amorphous SiO2 obtained from bamboo leaf ash (BLA) and CaO derived from meretix meretix shell (MMS) using solid state reaction. Amorphous SiO2 utilization in this work obtained by precipitation of BLA and calcined at 700o C for 3 h, whereas CaO MMS was generated by calcination of MMS at 1000o C for 5 h. High purity amorphous SiO2 obtained was 99.325 wt % and CaO purity obtained was 97.531 wt %. Single phase of β-wollastonite found in this study as confirmed by XRD results. The vibrations at 933.42, 904.49, and 890.99 cm-1 were caused by the Si-O-Ca bond, which shows the bonding of β-wollastonite obtained from the FTIR. The acicular morphology of β-wollastonite with average grains size of 0.28,0.33 and 0.71 µm was obtained for the samples calcined at 900, 1000, and 1100o C respectively.
