Structural Studies on New Superionic (AgI)0.8–(NaPO3)0.2 and (AgI)0.7–(NaPO3)0.3 at Room Temperature

Room temperature powder neutron diffractions have been performed to investigate the structure of (AgI) 0.8 – (NaPO 3 ) 0.2 and (AgI) 0.7 –(NaPO 3 ) 0.3 composites consisting of AgI crystalline precipitated in a glassy NaPO 3 network. Unlike (AgI) 0.8 –(NaPO 3 ) 0.2 and most silver-based superionic materials, (AgI) 0.7 –(NaPO 3 ) 0.3 contains Ag 5 IP 2 O 7 instead of βAgI and less γAgI. The diffuse background levels of both composites are similar and largely dominated by NaPO 3 amorphous phase.
