)PO4 materials are very stable at high temperature and water vapor partial pressure and they
show protonic conductivity; thus, they could be used as electrolytes in HTPFCs (high-temperature protonic
fuel cells), hydrogen sensors, and hydrogen separation technology. This work describes the combustion

)PO4 powders (x = 0, 0.025, 0.050) from mixtures of La(NO3)3·6H2O and Sr(NO3)2 as cation precursors, (NH4)2HPO4 as anion precursor, and urea as fuel. The characterization of
the as-prepared combustion products showed that combustion synthesis provides a straightforward method
for the achievement of solid solutions of these materials as nanometric powders. Furthermore, dilatometric
studies reveal that dense ceramics can be obtained at low sintering temperature (1300 °C), in air, from
the synthesized nanometric powders.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
