In this paper, the influence of coal bottom ash and tincal additions on the physical properties and microstructures of the standard wall tile body composition was investigated. Water absorption, firing strength, dry and fired shrinkage tests of the incorporated ceramic bodies and reference body were done. Microstructures of sintered tiles were analyzed using a scanning electron microscope (SEM). The results show that tincal additions to the ceramic body improved the physical properties of the tiles. As a result, tincal can be used as a flux material in the ceramic bodies due to its favorable effects on the water absorption and fired strength. The results revealed that bottom ash can be used in the ceramic tile body composition. When bottom ash was used in the ceramic industry, environmental hazards of bottom ash are inhibited. Furthermore, bottom ash is transformed to an economic product.

Effects of the addition of ulexite to the sintering behavior of a ceramic body
Salih Ugur Bayca 한양대학교 세라믹연구소 2009 Journal of Ceramic Processing Research Vol.10 No.2
The aim of this study was to investigate the effects of the addition of ulexite to the sintering behavior of a ceramic body. Ulexite is a boron mineral that is known as sodium calcium borate. The effects of ulexite, as a powerful flux, on the properties such as the water absorption, bending strength, and shrinkage and on the colors of ceramic tiles were studied. The microstructures of a standard and tiles with the additive were analyzed using a scanning electron microscope (SEM). The properties of with ulexite added tiles were compared with that of standard tiles and it was concluded that tiles having the additive had more favorable physical properties than the standard ones. Adding ulexite decreased the sintering temperature of the tiles, which in turn led to an increase in the bending strength of the tiles, a decrease in water absorption, and an increase in shrinkage. The SEM analyses have shown that ulexite additions increased the vitrification in the body.
