Solid State Communications | 1997

High pressure X-ray diffraction study of β-Si3N4

Yingjiu Li; M. B. Kruger; Johnny Nguyen; Wendell A. Caldwell; Raymond Jeanloz

Abstract X-ray diffraction data collected at quasi-hydrostatic pressures of 5–34 GPa yield an average zero-pressure bulk modulus and pressure derivative of K 0 = 270(±5) GPa and K 0 ′ = 4.0(±1.8) for β-Si 3 N 4 at room temperature. Similar linear incompressibilities along the a and c crystallographic directions document that compression is nearly isotropic.
