Metastable cubic and tetragonal zirconium dioxide, prepared by thermal oxidation of the dichalcogenides

The reactions of zirconium disulfide and zirconium diselenide with air or oxygen have been studied. They proceed topotactically and yield nanocrystalline, nanoporous metastable cubic and tetragonal zirconium dioxide at temperatures considerably below their stability range. This synthetic passway may...

Zusammenfassung:The reactions of zirconium disulfide and zirconium diselenide with air or oxygen have been studied. They proceed topotactically and yield nanocrystalline, nanoporous metastable cubic and tetragonal zirconium dioxide at temperatures considerably below their stability range. This synthetic passway may therefore be considered to belong to the field of soft chemistry.
