    Abstract
    This project is focused on the production of wollastonite (CaSiO3) from local resources. Wollastonite was produced by milling silica (SiO2) and limestone (CaCO3) in planetary mill for 1 and 5 hours. Samples have been sintered at different temperatures which are 900°C, 1100°C and 1300°C for 1 hour. The raw materials that have been used was collected from surround of state of Perlis and have high purity. This has been proven by X-Ray Fluorescence (XRF) analysis. By observing under Scanning Electron Microscope (SEM), the morphology of wollastonite shows that it has high porosity and disperses homogeneously. The X-Ray Diffraction (XRD) pattern shows that the phase of β wollastonite occurred almost at high temperature which is 1100°C. Besides, the intensity of peak also shows that the wollastonite has crystalline structure. The C-O and C-C bonding is proven by Fourier Transform Infra-Red (FTIR) analysis. The particle size for 1h milling is 26.16μm while for 5h is 16.8μm.
