Thermophysical Properties of Solutions of Iron (III) Nitrate-Nonahydrate in Mixtures of Ethanol and Water

Abstract

The quality of nanoparticles that are obtained by spray flame synthesis dependsstrongly on the thermophysical properties of the precursor solutions. Solutions ofiron(III)nitrate-nonahydrate (INN) in ethanol are interesting precursor solutions forthe production of iron oxide nanoparticles in these processes. However, no data onthermophysical properties of solutions of INN in ethanol are available in theliterature. Therefore, in the present work, the specific density, viscosity, thermalconductivity and molar isobaric heat capacity of solutions of INN in solvent mixturesof 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 upto 1.3 mol kg-1. Empirical correlations of the experimental data are provided.
