Abstract The Na 2 Zr(PO 4 ) 2 with morphologies of microflower or square-like sheet were prepared from phosphate solution and zirconium oxychloride by hydrothermal treatment at 180 °C for a short time. It was found that the different phosphate solution conditions played a vital role in crystal growth of Na 2 Zr(PO 4 ) 2 .

High‐Temperature Zirconium Phosphates
Journal of the American Ceramic Society, 1954The existence of two zirconium phosphate compounds has been established. The “normal” phosphate, ZrP 2 O 7 , has a reversible inversion at 300 °C. and dissociates to the zirconyl compound, (ZrO) 2 P

Polyaniline intercalated into zeolites, zirconium phosphate and zirconium arsenate
Journal of Physical Organic Chemistry, 1994AbstractAniline (or aniline hydrochloride) was intercalated into zeolite, zirconium phosphate and zirconium arsenate (proton form and sodium form) and subsequently oxidized to polyaniline (PAN) by ammonium peroxodisulphate. The structure of PAN in the host was studied by electron paramagnetic resonance spectroscopy.

Acidity of crystalline zirconium phosphate
Journal of Inorganic and Nuclear Chemistry, 1978Abstract The acid strength distribution has been measured for the crystalline zirconium phosphate thermally treated at various temperatures. There are two types of acids with remarkably different strength of acidity from one another; +4.8 ≥ Ho ≥ + 3.3 and −3.0 ≥Ho ≥−5.6.

Zirconium phosphate ester interchange reactions
Journal of the Chemical Society, Dalton Transactions, 1989α-Zirconium phosphate was demonstrated to undergo ester-interchange reactions with alkyl phosphate groups. Partial interchange was found to occur in neat alkyl phosphate solutions. However, complete exchange is possible if the interlayer spacing of α-zirconium phosphate is first enlarged by intercalating an amine.

Zirconium phosphate–phosphite containing silica
Solid State Ionics, 1997Abstract Based on earlier experiences with α- and γ-zirconium phosphate, zirconium phosphate–phosphite (ZrPP) containing silica (ZrSiPP) has been prepared, and its structure identified by XRD. The thermal behaviour and specific surface area have also been determined.

Synthesis of sodium zirconium phosphates
Polyhedron, 1986Abstract Zr(O3PONa)2 · nH2O can be prepared as a single crystalline phase by direct precipitation in the presence of HF. This material is a powder. When a single crystal of α-HZrP is exchanged with Na+, Zr(O3PONa)2 · nH2O is obtained as a powder-like crystal.

Ion‐exchange Properties of γ‐Zirconium Phosphate
Chemistry – An Asian Journal, 2020Abstractγ‐Zirconium phosphate (γ‐ZrP) has potential as a very useful inorganic ion‐exchanger due to its stability under thermal and acidic conditions. We recently reported its facile synthesis using a modified solventless method, which could make the exploitation of its ion‐exchange properties for cleanup of radioactive materials and extraction of ...
