We have found three types of fluorite structure: the x = 0 end member of the solid solution (Y0.15Zr0.85O1.93) shows evidence of tetragonal fluorite-type structure; we have also observed a modulated fluorite-type structure due to short-range ordering of the oxygen vacancies. The microdomain modulated structure gradually evolves from a distorted pyrochlore-type to a type intermediate between C-type and distorted pyrochlore as x decreases from 1 to 0.3.engjournal articlehttps://doi.org/10.1039/B418557Ahttps://pubs.rsc.org/en/content/articlelanding/2005/jm/b418557aopen access54Ciencias23 Química
