Abstract

Next generation metal-ion conducting membranes are key to developing energy storage and utilization technologies like batteries and fuel ce lls. Sodium super-ionic conductors (aka NaSICON) are a class of compounds with AM 1 M 2 (PO 4 ) 3 stoichiometry where the choice of "A" and "M" cation varies widely. This report, which de scribes substitutional derivatives of NZP (NaZr 2 P 3 O 12 ), summarizes the accomplishments of a Laboratory D irected Research and Development (LDRD) project to analyze transport mec hanisms using a combination of in situ studies of structure, composition, and bonding, com bined with first principles theory and modeling. We developed an experimental platform and applied methods, such as synchrotron- based X-ray spectroscopies, to probe the electronic structure of compositionally well-controlled NaSICON films while in operation ( i.e ., conducting Na ions exposed to oxygen or water va por atmospheres). First principles theory and modeling were used to interpret the experimental observations and develop an enhanced understanding of atomistic processes that give rise to, and affect, ion conduction.

NANOSTRUCTURED CERAMICS AND COMPOSITES FOR REFRACTORY APPLICATIONS IN COAL GASIFICATION

Technical Report Brown, Paul

A class of ceramics, capable of exhibiting low coefficients of thermal expansion and catalytic properties was investigated. Investigations were directed towards nanoengineering of NZP ceramics and NZP-based composites by chemical means by controlling their compositions and processing variables. NaZr{sub 2}(PO{sub 4}){sub 3} (NZP) was synthesized by combining water-soluble precursors leading to the precipitation of a gel that was dried, calcined, pressed into pellets, then fired at 850 C. Without chemical additives, the resulting ceramic comprised pores ranging in size from approximately 25 to 50 nm and a surface area of about 30m{sup 2}/g. Hydroxyapatite, which has a needle-like morphology, wasmore »« less

Ionic conductivity and sinterability of NASICON-type ceramics: The systems NaM{sub 2} (PO{sub 4}){sub 3} + yNa{sub 2}O (M = Ge, Ti, Hf, and Zr)

Journal Article Aono, Hiromichi; Sugimoto, Eisuke - Journal of the American Ceramic Society

Sodium-rich NASICON-type ceramics, the NaM{sub 2}(PO{sub 4}){sub 3} + yNa{sub 2}O (M = Ge, Ti, Hf, Zr) systems, were investigated in order to obtain a material having a high Na{sup +} conductivity and high density. The ionic conductivity and the sinterability were greatly improved by an increase in the value of y for all of the systems examined. Added Na{sub 2}O was not soluble in the NASICON-type skeleton, since the lattice constants and the X-ray diffraction patterns were not changed by the Na{sub 2}O addition in all of the samples. Na{sub 2}O acts as a flux for obtaining highly densemore »« less
Enhanced alkaline stability in a hafnium-substituted NaSICON ion conductor

Journal Article Small, Leo; Wheeler, Jill; Ihlefeld, Jon; ... - Journal of Materials Chemistry. A

In this paper, we present a multi-length scale integration of compositionally tailored NaSICON-based Na⁺ conductors to create a high Na⁺ conductivity system resistant to chemical attack in strongly alkaline aqueous environments. Using the Pourbaix Atlas as a generalized guide to chemical stability, we identify NaHf₂P₃O₁₂ (NHP) as a candidate NaSICON material for enhanced chemical stability at pH > 12, and demonstrate the stability of NHP powders under accelerated aging conditions of 80 °C and pH = 13–15 for a variety of alkali metal cations. To compensate for the relatively low ionic conductivity of NHP, we develop a new low temperaturemore »« less

Lattice Dynamics in the NASICON NaZr ₂ (PO ₄ ) ₃ Solid Electrolyte from Temperature-Dependent Neutron Diffraction, NMR, and Ab Initio Computational Studies

Journal Article Morgan, Emily; Evans, Hayden; Pilar, Kartik; ... - Chemistry of Materials

Natrium super ionic conductor (NASICON) compounds form a rich and highly chemically tunable family of crystalline materials that are of widespread interest because they include exemplars with high ionic conductivity, low thermal expansion, and redox tunability. This makes them suitable candidates for applications ranging from solid-state batteries to nuclear waste storage materials. The key to an understanding of these properties, including the origins of effective cation transport and low, anisotropic (and sometimes negative) thermal expansion, lies in the lattice dynamics associated with specific details of the crystal structure. Here we closely examine the prototypical NASICON compound, NaZr₂(PO₄)₃, and obtain detailedmore »« less

Preparation of monophasic [NZP] radiophases: Potential host matrices for the immobilization of reprocessed commercial high-level wastes

Conference Hawkins, H; Guthrie, Jr, G; Scheetz, B

The compositional flexibility of the sodium zirconium phosphate (NaZr{sub 2}(PO{sub 4}){sub 3}) structure has been exploited in the design of monophasic radiophases capable of immobilizing the most common cations associated with reprocessed high-level commercial waste streams. Highly crystalline, monophasic members of the NaZr{sub 2}(PO{sub 4}){sub 3} structural family ([NZP]) have been prepared with conventional processing methods and equipment. These radiophases were tailored to accommodate 10--20 wt% modified PW-4b simulated calcine as single phases isostructural with NaZr{sub 2}(PO{sub 4}){sub 3}. To meet the challenge of designing monophasic materials capable of accommodating the chemical complexity of PW-4b, an ionic substitution scheme basedmore »« less
