Résumé:
This work was focused on a comparative study of the optical characteristics between two types
of glass, the Titanium-based MEDIREFLECT (Ti, TiOx ...) and the Niobium-based MEDIREFLECT
(NbOx) in the aim to improve their optical and energetic properties all while maintaining their
qualitative properties.
After reviewing the literature on Ti and Nb-based glasses and taking into consideration the
desired properties such as transmission, reflection, refractive index, thermal conductivity and light
absorption capacity, the samples were characterized through different techniques to evaluate their
optical and energetic properties. Tests had been made, one of them being the resistance of abrasion
and corrosion, UV aging, thermal quenching test, salt spray ... etc.
The results have showed that the NbOx-based MEDIREFLECT led to the improvement of the
qualitative properties while maintaining the energetic, optical and durability properties.
