Synthesis of Sr-based Silicides and Related Compounds using CaSi2 Crystal Powders
Abstract
Strontium-based silicides and related compounds were synthesized by annealing mixtures of CaSi₂, MgCl₂, and Sr powders under an Ar atmosphere. Flake-shaped SrCaSi sheets were formed at 800 °C, whereas stacked nanosheet-like α-SrSi₂ structures were obtained at 1000 °C. The reaction was strongly dependent on the temperature and source ratios, yielding layered silicides together with carbonate byproducts. When mixed sources were used, SrCO₃ was mainly formed, whereas in the Sr–Si system, SrSi₂ appeared as the dominant phase despite the presence of other secondary products. These results demonstrate that careful control of the starting composition and annealing conditions enables the selective growth of layered Sr–Si compounds.
