In this investigation, SnO2-glass composites were produced by mixing SnO2 and amorphous silica xerogel (SX) extracted from sago waste ash. The composition was prepared by adding 5 mol% of SnO2 into SX; the samples were dry pressed and sintered in a temperature range between room temperature and 1500oC. Their properties were characterized on the basis of the experimental data obtained using Archimedes’ principle, X-ray diffraction (XRD), Fourier transformed infra-red (FTIR), and a scanning electron microscopy ...

This investigation presents the synthesis procedure and the results of an investigation of the crystallite growth of TiO2 and the formation of Si–O–Ti bonds in novel silica xerogel (SiO2) glass ceramic produced from an amorphous SX derived from sago waste ash. The composition had been prepared by adding various amounts of TiO2, from 20 wt% to 80 wt%, into the amorphous SiO2, and then a series of samples were sintered at 1200°C for 2 hours. ...
