Notes:
Aiming identification of the components most affected by corrosion under salineenvironment conditions, we have carried out X-ray diffraction measurements in ceramic and bondmaterials, all in the powder form. The ceramic is analyzed before and after thermal annealing at1000ºC, showing the same DRX peaks, although better defined after annealing. Identificationsuggests the presence of Al6Si2O13 (Mullite) and SiO2 (Quartz). Analysis of the junction (bond)material shows similar peaks, but a metallic preponderance is observed. Thermal annealing of thejunction is done at much lower temperature, because it melts in the range 135ºC-170ºC, when awhitish smoke begins to show up along with strong sulfur odor
