Abstract :

This article presents the use of diffuse reflectance infrared Fourier transform (DRIFT) spectroscopic technique in investigation of the effect of thermal activation on morphology of perlite. Perlite, a naturally occurring waste siliceous material formed by rapid cooling of volcanic eruptions was thermally treated over a range of temperatures. This study focuses on changes in both structure and chemical bonding of perlite due to thermal activation at different temperatures viz., 400, 600, 800, 1000°C for certain time period. The results reveal that on increasing temperature of thermal activation, loss of water occurs which is confirmed by decrease in intensity and oadness of the band, appears between 3600–3300 cm–1, attributing to surface –OH groups. Other bands present in the DRIFT spectra shows the presence of Si–O–Si network and amorphous nature of silica in perlite.
