Chemistry in Molten Salts: A Suitable Route for the Preparation of Submicronic Oxide Powders

摘要

Oxide powders, precipitated by reaction of transition metal salts precursors with molten alkali metal nitrates or nitrites, in the temperature range 400-500℃ are characterized by a very good chemical homogeneity and a purity satisfying for applications in heterogeneous catalysis and as starting material for ceramics. They are constituted of submicronic aggbmerates often including nano-sized crystallites.
