Abstract
Proton transport in ammonium para-tungstate pentahydrate (NH4)10W12O41.5H2O (APT.5H2O) has been established using coulometry transient ionic current IR and electrical conductivity measurements along with the TGA/DTA results of Kiss and co-workers. The mobile ions are NH4+, H+ and O2-. The ions (H+ and O2-) are the products of electrolysis of the inter-layer water. The temperature dependence of the electrical conductivity has been correlated with the accompanying dehydration and de-ammoniation reaction of APT.5H2O.Keywords
