Structural Properties of Cullet-Paper Ash-Kaolin Clay Ceramic

This study focused on the structural properties of (x) Paper ash-(80-x) Cullet-20 Kaolin clay ceramic that are synthesized by solid state reaction due to the cullet content. The crystallinity and structure were determined using X-Ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopy. The major phase of the ceramic was Wollastonite (CaSiO3) while the minor phase consisted of Dicalcium Silicate (Ca2SiO4) and Quartz (SiO2). The FTIR spectra of the S2 sample exhibited broad peak near to 1020cm^-1 corresponding to the stretching vibration of Si-O-Si linkage. The changes of Raman spectra linewidth of the S2 sample were observed near 575cm^-1, 480cm^-1 and 968cm^-1 which attributed to the Si-O-Si stretching respectively. (paper)
