Abstract

Single crystals of CrSi2 were obtained in the form of hexagonal prisms by the solution growth method using molten tin as a flux. The maximum size of the crystal is about 0.3mm in diameter and 25mm in length. The crystal structure of CrSi2 has hexagonal symmetry with space group P6 222 and the lattice parameters are a=0.425(2)nm and c=0.6375(1)nm, respectively. The crystals are semiconducting. The value of the micro-Vickers hardness for the {11̄00} face with hexagonal symmetry is 11.2±0.4GPa. Weight gain of the crystals heated up to 1473K in air is negligible.
