Abstract

Abstract: In this work, microsized cubic BP particles was produced by vacuum-sealed solid state reaction. X-ray diffraction Rietveld refinement and x-ray photoelectron spectroscopy results indicate the prepared BP particles are highly crystalline and high purity. In-situ x-ray diffraction and Raman measurements under high pressure show the cubic BP particles possess high structural stability up to 36.0 GPa with high reversible structure recovering ability. Meanwhile, a high bulk modulus of 205(2) GPa and pressure derivative B 0 ′ of 3.8(1) are obtained from in situ x-ray diffraction measurements. Grüneisen parameters of 1.01 and 1.17, and the pressure coefficient d ω /dp = 4.07 and 4.57 cm −1 /GPa for LO and TO mode, respectively, are also deduced from Raman measurements under various high pressure.
