Determining the Phase Composition of Copper Ferrite Samples by a Standardless Differential Dissolution Method

  • Published:
Inorganic Materials Aims and scope

Abstract—

This paper reports the use of a differential dissolution stoichiographic method for determining the phase composition of catalysts for ammine borane hydrolysis and hydrothermolysis [1, 2]. Cu1–xFe2+xO4 copper ferrite samples were prepared using layer-by-layer combustion, dried, and then calcined at different temperatures. We describe conditions that make it possible to detect and quantitatively determine various phases in the composition of amorphous and crystalline materials with the spinel structure and compare differential dissolution and X-ray diffraction results.
