WebFeb 7, 2011 · The high amount of tetragonal crystal phase (> 90%) in Y-TZP causes birefringence, which is a type of crystal with different refractive indices based on its crystallographic orientation in the ... Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light. These optically anisotropic materials are said to be birefringent (or birefractive). The birefringence is often quantified as the maximum difference between refractive indices exhibited by the material. Crystals with non-cubic crystal structures are o…
