# Equation of state of boron subarsenide B12As2 to 47 GPa

## TL;DR

This study investigates the compressibility and equation of state of boron subarsenide B12As2 under high pressure up to 47 GPa, finding its bulk modulus and confirming structural stability without phase transitions.

## Contribution

First measurement of B12As2's equation of state up to 47 GPa using synchrotron X-ray diffraction, providing key data on its compressibility and structural stability.

## Key findings

- Bulk modulus of 150 GPa
- No pressure-induced phase transitions observed
- First EOS data for B12As2 up to 47 GPa

## Abstract

Compressibility of boron subarsenide B12As2 has been studied by synchrotron X-ray diffraction up to 47 GPa at room temperature in a diamond anvil cell using Ne pressure transmitting medium. A fit of experimental p-V data by Vinet equation of state yielded the bulk modulus of 150(4) GPa and its first pressure derivative of 6.4(3). No pressure-induced phase transitions have been observed.
