Abstract

In this study, β-wollastonite is produced from a reaction between silica (SiO2) and calcium oxide (CaO) with the SiO2/Cao ratio of 55:45. Rice straw ash is chosen as the source for SiO2 instead of rice husk ash because the straw can yield up to 85% of silica even though this percentage is lower than those silica yielded from rice husk ash. It is found that period of autoclaving and sintering play an important role in producing the wollastonite. As shown in the XRD results, a single phase β-wollastonite is obtained after 8 h of autoclaving and 3 h of sintering at 950 °C. The produced β-wollastonite phase also shows a good crystallinity but needs longer sintering time compared with wollastonite produced using rice husk ash. DTA graph shows a chemical reaction between silica and calcium oxide started to occur at 788.3°C. IR spectroscopic analysis data confirm that the IR peaks at 681, 894 and 931 cm-1 are due to the β-Wollastonite phase. Form the results obtained, it can be concluded that rice straw ash is comparable to rice husk ash as a precursor in producing β-Wollastonite material.
