Low-vacuum SEM analyses of ceramic tiles with emphasis on glaze defects characterisation
- Slovenian National Building and Civil Engineering Institute, Dimiceva 12, 1000 Ljubljana (Slovenia)
The behaviour of glazed building ceramics exposed to different environment (weathering, chemicals, etc.) is determined by microstructural features; in many cases structural and surface defects at the micro- or nanometre scale are crucial for the functional properties of products. Many testing methods for materials characterization of a variety of ceramic products, physical and chemical methods, are time-consuming, large quantities of samples are needed, and are usually destructive. This paper illustrates the use of low-vacuum scanning electron microscopy (LV-SEM) as fast and almost non-destructive, as only a small amount of sample is needed. Examples are given of various surface and structural properties of building ceramics, for the identification of the material deterioration process as a result of environmental impact.
