Abstract
This study investigated a new production technology for Iznik tiles. High quartz content of Iznik tiles was kept as it was and hydraulic pressing instead of tapping was used for shaping. Besides the traditional pouring technique, tiles were also glazed by spray coating. Characterization of the Iznik tiles were approached using different methodologies, including scanning electron microscopy plus energy dispersive X-ray spectrometry (SEM-EDX), Raman spectroscopy, atomic force microscopy (AFM), X-ray diffractometry (XRD) and dilatometry. Characterization results revealed that thermal expansion coefficients (TECs) of body, slip layer (thinned siliceous clay) and frit are 8.41, 8.48 and 8.32 × 10−6 K−1, respectively, and matched which is fundamental to achieve increase in strength and keep the glaze in compressive stress. Raman signatures of the Iznik tiles agreed with the literature information. By double layer spray coating, smoother surfaces can be obtained on Iznik tiles than by traditional method of glazing.
Kurzfassung
In der diesem Beitrag zugrunde liegenden Studie wurde eine neue Produktionstechnik für Iznik-Fliesen untersucht. Hierbei wurde der hohe Quarzanteil der Iznik-Fliesen beibehalten und es wurde hydraulisches Pressen statt Abstechen zur Formgebung eingesetzt. Neben der traditionellen Gießtechnik, wurden die Fliesen außerdem mittels Sprühbeschichtens glasiert. Die Charakterisierung der Iznik-Fliesen wurde mit verschiedenen Verfahren, wie Rasterelektronenmikroskopie sowie Energiedispersiver Röntgenspektrometrie (SEM-EDX), Ramanspektroskopie, Rasterkraftmikroskopie, Röntgendiffraktometrie und Dilatometrie, realisiert. Die thermischen Ausdehungskoeffizienten des Fliesenkörpers, der dünnen Silikatschicht und der Glasiermasse betrugen 8,41, 8,48 und 8,32 × 10−6 K−1 und passten gut zueinander, was sich als grundsätzliche Voraussetzung erwies, um eine Zunahme der Festigkeit zu erreichen und um die Glasur unter Druckspannung zu halten. Die Ramandiagramme der Iznik-Fliesen stimmten mit den Informationen aus der Literatur überein. Durch Doppellagen-Sprühbeschichtung konnten weichere Oberflächen auf den Iznik-Fliesen erzielt werden als durch das tradionelle Verfahren des Glasierens.
