Abstract

We have studied the thermal expansion of CaIr4B4, IrB1.1, and CaB6. The results demonstrate that the crystal lattices of these phases expand linearly with temperature and that their thermal expansion coefficients lie in the range (5–10) × 10–6 K–1. We have determined the average microhardness of the CaIr4B4, IrB1.1, and CaB6 phases. The average microhardness of the CaIr4B4 phase is ~15 GPa, which is a factor of 3 lower than that of the CaB6 phase
