High Pressure High Temperature Study of B+Sb Mixture
Abstract
High pressure synthesis of BSb has been attempted using Laser Heated Diamond Anvil Cell facility with a CO2 laser. B:Sb in 3:1 atom ratio was laser heated at ∼7 GPa , 10 GPa and 30 GPa. In-situ characterization of the pressurized sample was done by micro-Raman technique. The micro-Raman results before and after laser heating at different pressures did not indicate compound formation. Also, Sb, which shows a series of structural transitions under pressure up to 30 GPa did not show any metastable phase in the P and T regime studied.
