The quality of nanoparticles
that are obtained by spray flame synthesis
depends strongly on the thermophysical properties of the precursor
solutions. Solutions of iron(III) nitrate-nonahydrate (INN) in ethanol
are interesting precursor solutions for the production of iron oxide
nanoparticles in these processes. However, no data on the thermophysical
properties of solutions of INN in ethanol are available in the literature.
Therefore, in the present work, the specific density, viscosity, thermal
conductivity, and molar isobaric heat capacity of solutions of INN
in solvent mixtures of ethanol and water were measured at 101.3 kPa
between 288.15 and 333.15 K, solvent compositions ranging from pure
ethanol to pure water, and INN molalities up to 1.3 mol kg–1. Empirical correlations of the experimental data are provided.
