(FR) PHOSPHATE DE SILICIUM ET MEMBRANE LE COMPRENANT
Abstract
(EN)
The invention provides a composition having the formula (I): xXO2.yY2O5, (wherein: 0.5 < x < 0.7; 0.3 < y < 0.5; X comprises one or more of silicon, titanium, germanium and zirconium; and Y comprises one or more of phosphorus, vanadium arsenic and antimony), or a hydrate thereof, in which the composition comprises more than 50 wt% or more of crystalline material.
(FR)
L'invention porte sur une composition représentée par la formule (I) : xXO2.yY2O5, (dans laquelle : 0,5 < x < 0,7; 0,3 < y < 0,5; X représente le silicium et/ou le titane et/ou le germanium et/ou le zirconium; et Y représente le phosphore et/ou le vanadium et/ou l'arsenic et/ou l'antimoine), ou un hydrate de celle-ci, la composition comprenant plus de 50 % en poids de matière cristalline.
