Nanocrystalline chromium disilicide synthesized by a fast Chlorine-Transfer-Reaction

摘要

Pure nanocrystalline chromium disilicide (CrSi2) were synthesized for the first time by a fast ChlorineTransfer-Reaction between chromium chloride and silicon with the support of thermodynamics calculation. The use of sodium and lithium chloride diluent enables to decrease the aggregates size from similar to 2000 nm to similar to 500 nm and to reach a nanocrystallite size ranging from 50 to 200 nm suitable for new applications.
