WebA 31 P NMR study of a wider range of zinc phosphate glass compositions has shown that the ultraphosphates contain mainly ring structures whereas only chain units are present in the zinc metaphosphate glasses ( Wiench et al. 2000 ). Zirconium phosphates (zirconium hydrogen phosphate) are acidic, inorganic cation exchange materials that have a layered structure with formula Zr(HPO4)2∙nH2O. These salts have high thermal and chemical stability, solid state ion conductivity, resistance to ionizing radiation, and the capacity to incorporate different types of molecules with different sizes between their layers. There are various phases of zirconium phosphate which vary in their interlaminar spaces and the…
