Effects of quartz grain size distribution on the structure of porcelain glaze

This paper discusses the effects of quartz grain size on the structure of porcelain ceramic glazes. Individual compositions of white opaque ceramic glaze for sanitary ware contained quartz powder of different grain sizes from 8.33 µm to 0.27 µm. The structure of the glazes was analyzed using FTIR spectroscopy of the phase composition and microscopic imaging using SEM-EDAX and confocal laser scanning microscopy. It was shown that the use of quartz of a very fine grain size increases the degree of disordering of the glaze by increasing the number of non-bridging oxygen atoms.
