Kinetics of gas-solid reactions in α-zirconium phosphate. H+/Na+ mixed diffusion coefficients

Publikováno v: Journal of Inorganic and Nuclear Chemistry. 43:2117-2120

The rates of reaction between gaseous HCl and sodium ion exchanged phases of α-zirconium phosphate have been measured. The reactions are diffusion controlled and were fit by an equation for diffusion in a sphere from a well stirred fluid of limited

The use of hydrothermal procedures to synthesize NASICON and some comments on the stoichiometry of NASICON phases

Autor: W. Wang, M.A. Subramanian, Abraham Clearfield, P. Jerus

Publikováno v: Solid State Ionics. :895-902

NASICON was prepared by a two step process. In the first step zirconium phosphate an Na 4 SiO 4 are treated hydrothermally at 300°C. This produced a hydrated phase with approximate composition Na 4 Zr 2 Si 2.25 P 1.8 O 15 ·H 2 O which could be inde

Ionic conductivities of phosphorus-substituted β-eucryptite ceramics

Autor: P. Jerus, R.M. Tindwa, Abraham Clearfield, A.J. Perrotta

Publikováno v: Materials Research Bulletin. 17:873-881

Lithium ion conduction in β-eucryptite (LiAlSiO 4 ) and β-eucryptite-AlPO 4 solid solutions has been investigated by an ac impedance method between 423°K and 673°K over a frequency domain of 10 Hz - 500 kHz. Adding AlPO 4 increases conductivity a

Preparation Techniques for Hydrotreating Catalysts and Their Influence on the Location of the Metal Oxides and Performance

Autor: A. L. Hausberger, E. K. Dienes, W. M. Keely, P. Jerus

Publikováno v: Catalysis Reviews. 26:485-502

There have been many studies in the last 30 years on hydrotreating catalysts. The early studies involve various metals and supports and their influence on activity. Later studies have applied bulk and surface analytical techniques to defining the str
