Abstract
The bulk modulus of β-boron has been measured up to 10 GPa by neutron powder diffraction using an opposed-anvil pressure cell. The bulk modulus of α-boron has also been measured to 5 GPa by single-crystal x-ray techniques. The values have been determined to be 185(7) GPa for β-boron and 224(15) GPa for α-boron. These values are markedly smaller than those measured for other hard materials, but total-energy calculations for α-boron are in reasonable agreement.Keywords
