Abstract

Microwave-hydrothermal (M − H) synthesis of α-Sn(HPO₄)₂·H₂O (α-SnP) was achieved here in as low as 5 min at 194 °C compared to several days by others previously. The use of microwaves in conjunction with the hydrothermal process enhanced the α-SnP synthesis reaction at least by two orders of magnitude. The super fast synthesis was apparently due to localized superheating where nucleation started and the reactions occurred very quickly in the localized superheated spots. The synthesized α-SnP was characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). TEM revealed worm-like morphology at both low temperature and short duration of M − H treatment but at higher temperature platy morphology typical of layered phases resulted. The synthetic tin phosphate (α-SnP) phase is potentially useful as a cation exchanger, proton conductor and electrode material.
