Infrared and Raman Spectroscopy of Mullite Ceramics Synthesized from Fly Ash and Kaolin
Original language description
Infrared spectroscopy and Raman spectroscopy were used to characterize mullite ceramics prepared from fly ash and kaolin by annealing at 1000 oC, 1100 oC, 1200 oC, and 1300 oC. IR spectroscopy confirmed the presence of SiO4 tetrahedra and AlO6 octahedra in samples. The presence of mullite has been confirmed at all temperatures. The presence of quartz has been confirmed up to a temperature of 1100 oC, and the presence of an amorphous form of SiO2 has been confirmed at temperatures of 1200 oC and 1300 oC. The transformation of quartz into the amorphous form of SiO2 at temperatures above 1100 oC is assumed. Transformation was performed on the percentage intensity decrease of the bending vibration of Si-O-Si (at about 450 cmMINUS SIGN 1) and Al-O-Si (at about 550 cmMINUS SIGN 1). Raman spectroscopy confirmed the presence of mullite at different stages of structural ordering (a well-ordered structure at a temperature of 1100 oC and a disordered structure at a temperature of 1300 oC).
