Resumo: Aiming identification of the components most affected by corrosion under saline environment conditions, we have carried out X-ray diffraction measurements in ceramic and bond materials, all in the powder form. The ceramic is analyzed before and after thermal annealing at 1000°C, showing the same DRX peaks, although better defined after annealing. Identification suggests the presence of Al6Si2O13 (Mullite) and SiO 2 (Quartz). Analysis of the junction (bond) material shows similar peaks, but a metallic preponderance is observed. Thermal annealing of the junction is done at much lower temperature, because it melts in the range 135°C-170°C, when a whitish smoke begins to show up along with strong sulfur odor.
