Synthesis and properties of yttrium hydroxyacetate sols

Inorganic Materials Aims and scope

Abstract

We report a process for the preparation of yttrium hydroxyacetate sols by sonicating yttria nanopowder in aqueous acetic acid. The dependences of the rheological characteristics and electrokinetic potential of the sols on the pH of the medium and the concentration of chloride and sulfate anions are used to identify the mechanism underlying the coagulation stability of the sols. The thermal decomposition of the yttrium hydroxyacetate xerogel obtained by drying the sol is analyzed in detail.
