Journal ArticleDOI
New crystalline phases of zirconium phosphate possessing ion-exchange properties
TL;DR: In this article, the preparation of two new crystalline zirconium phosphates, Zr(HPO4)2 and Zr[H20]2 · 2H2O, is reported.
Journal ArticleDOI
The preparation and crystal structure of a basic zirconium molybdate and its relationship to ion exchange gels
A. Clearfield,Robert H. Blessing +1 more
TL;DR: In this article, the crystal structure of zirconium molybdate was determined from integrated precession photographs using MoKα radiation, and a three-dimensional network of cross-linked chains built-up of quite regular [ZrO 3 eq (OH 2 eq O 2 ax ]-pentagonal bipyramids and distorted cis -MoO 4 (OH)(H 2 O-octahedra).
Journal ArticleDOI
On the mechanism of ion exchange in zirconium phosphates—XIII: Exchange of some divalent transition metal ions on α-zirconium phosphate
A. Clearfield,John M. Kalnins +1 more
TL;DR: The exchange of Mn(II, Co(II), Ni(II) and Zn(II)-on crystalline zirconium phosphate has been examined in this article, where the exchange does not represent a true equilibrium since the site binding traps the ions within the crystal lattice.
Journal ArticleDOI
Factors determining ion exchange selectivity—I high temperature phases formed by α-zirconium phosphate and its sodium and potassium exchanged forms☆
A. Clearfield,Sung Pill Pack +1 more
TL;DR: In this paper, the phases formed at elevated temperatures by α-zirconium phosphate (α-ZrP) and its partially exchanged sodium and potassium ion phases have been determined by a combination of thermal and X-ray methods.
Journal ArticleDOI
On the mechanism of ion exchange in crystalline zirconium phosphates - IV potassium ion exchange of α-zirconium phosphate
TL;DR: In this paper, the ion exchange behavior of α-zirconium phosphate crystals titrated with potassium ion and the behavior of the potassium-exchanged forms with HCl has been examined.
