Synthesis, Crystal Structure, and Compressibilities of Mn Ir B (0≤x≤0.5) and Mn IrB.

The new ternary transition metal borides Mn Ir B (0≤x≤0.5) and Mn IrB were synthesized from the elements under high temperature and high-pressure/high-temperature conditions. Both phases can be synthesized as powder samples in a radio-frequency furnace in argon atmosphere.

High-Pressure Synthesis of β-IrB and Determination of the Compressibility of Various Iridium Borides.

A new iridium boride, β-IrB, was synthesized under high-pressure/high-temperature conditions of 10.5 GPa and 1500 °C in a multianvil press with a Walker-type module. The new modification β-IrB crystallizes in a new structure type in the orthorhombic space group Pnma (no.
