Structural and Microstructural Characterisation of Refractory Oxides Synthesised by Laser

Several ceramic materials have been chosen and synthesized by Selective Fusion by Laser (SFL). These materials have been selected because their refractory condition, high hardness and good colouring power, that make them useful to be used as ceramic pigments. In the present work it is shown the structural and microstructural characterisation of these materials prepared by Laser assisted synthesis, individually and into a vitreous matrix (glaze) and subjected to a firing cycle with a maximum (highest) temperature of 1200degreesC. The techniques used in the characterisation have been Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), thermal analysis as Differential Thermal Analysis (DTA) and Thermogravimetry (TG) and UV-Vis Spectroscopy to obtain their CIE-Lab chromatic coordinates.
