I. Dans-le-chapitre, En termes d'analyse, l'identification de ces deux phases pyro-chlores n'est pas évidente. Ces deux structures ont les même pics de caractérisation par la diffraction des rayons X : à 2theta=29,5° et à 2theta=34° présentant respectivement aux plans (004) et (022) de ces structures Fd3m, group 227. Par variation de la température de dépôt, nous voyons un pic apparaitre à 2theta=14° correspondant au plan (002) de la structure Fd3m accompagnant la décroissance de l'intensité du pic 2theta=34°, Nous supposons que nous stabilisons plutôt la pyro-chlore Pb 3 Nb 4 O 13 (liée à la perte du plomb) à haute température mais la coexistence des deux pyro-chlores en même temps est complètement possible. Nous n'avons ni le moyen technique ni le moyen d'analyse pour les séparer
