Sažetak
The forming and sintering of fumed silica powders is an interesting route for the preparation of large, very pure or doped silica glasses with a precise geometry. Here we have investigated the process of sintering of transparent silica glass by Raman spectroscopy. The main changes in the Raman spectra appeared in the range of defects lines D1 and D2. The changes in intensity of these lines are monitored by the process of sintering in oxygen, hydrogen, helium and water vapour as well as by crystallisation and remelting. The results fit the structure model with clusters and interclusters layer.
