Ceramic Tile Surfaces in Acid Environment: Study of the Topographic, Microstructural and Mechanical Changes

Glazed ceramic tiles are characterised by a good chemical durability excepting in highly alkaline and acid environment. A continual use of cleaning agents with a basic or acid pH on ceramic flooring, could give rise to a lowering of mechanical performances due to the corrosion of crystalline phases more than the
amorphous phase. In the present work, several glazed tile surfaces characterised by different microstructures (amorphous and partially crystallised) were considered. In order to better understand the mechanisms responsible of
the surface tiles ageing, the working surfaces, before and after chemical etching, were analysed from topographic, microstructural and mechanical point of view. Results showed that it is possible to correlate microstructural differences of ceramic surfaces before and after a chemical etching, with their physicalmechanical characteristics.
