In-Situ, in Air, High-Temperature Phase Transformations in Rare-Earth Niobates and Titanium Oxides (Dysprosium and Yttrium) Using a Thermal-Image Furnace
"The use of a co-existent ""in-situ thermometer"" was found to be a viable method to monitor the sample temperature in the image ""hot-spot"". Studies of YNbO4 and DyNbO4 revealed the existence of a new cubic phase at elevated temperatures beyond the commonly known ferroelastic …

Engineering of Alkali Metalorganic Precursors: Synthesis to Mechanistic Aspects
… especially for sodium and potassium. Lithium Niobates (LiNbO3), solid solutions of sodium and potassium niobates (KxNa1−xNbO3, KNN), and variants of these alkali niobates family are shown to be viable green alternatives for the current lead-containing piezo- and ferroelectric material, i.e., …

Sulfidation of Ternary Oxides: A Thermodynamic and Experimental Study Toward Selective Metal Extraction
… oxides of titanates, molybdates, tungstates, niobates, and tantalates. Modified predominance diagrams were constructed to determine the possible sulfidation outcomes, and a sensitivity analysis on the input thermodynamic data was performed to assess their impact on the outcome of sulfidation. …
