Abstract

In order to verify the possibility to use new glass ceramic materials as glazes for floor tiles, the devetrification process of a formulation belonging to the wollastonite stability field in the CaO-SiO2-ZrO2 system was investigated by DTA, XRD and SEM techniques. The investigated system shows a high tendency toward crystallisation, that brings to the separation, also at very high heating/cooling speed, of CaO·SiO2 (wollastonite) and 2CaO·ZrO2·4SiO2 (calcium and zirconium silicate) as main crystalline phases. Industrial tests demonstrate how the formulation can be used as prevalent component in the tile glaze preparation.
