Abstract

CaF₂ nanostructures were synthesized from Ca-silicide powders by a diluted aqueous HF treatment. Commercially-available CaSi₂ crystal powders and calcium silicide powders prepared by mechanical alloying were used as the source materials, and CaF₂ nanosheet bundles and nanobunches of the CaF₂ nanoparticles were obtained, respectively. The morphological property of the resulting CaF₂ nanostructures was characterized by electron microscopy. It was found that the morphology of the resulting products depended on the starting materials. In addition, the growth mechanism of the CaF₂ nanostructures was discussed from a topological synthesis point of view.
