A Pulsed Field Gradient Nuclear Magnetic Resonance Spectrometer for Direct Measurement of Ionic Diffusion in Solid Electrolytes.

Abstract

A pulsed field gradient nuclear magnetic resonance spectrometer was successfully constructed which is based on a superconducting magnet and has magic angle spinning capabilities. A dewar facility is an integral part of this system so as to permit investigation of ionic diffusion down to 77 K, along with a sample heating arrangement for diffusion measurements up to 300 C. This spectrometer has been employed in the measurements of protonic diffusion coefficients in beta -alumina solid electrolytes and cation, anion and self diffusion coefficients and amorphous polymeric electrolytes. Keywords: Nuclear Magnetic resonance; Spectrometer; Diffusion; Tons; Solid electrolytes.
