摘要
Almost absorption- and extinction-free single-crystal synchrotron X-ray diffraction data were measured at 150, 200 and 295 K for beta-Si3N4, silicon nitride, at a wavelength of 0.7 Angstrom. The true symmetry of this material has been the subject of minor controversy for several decades. No compelling evidence favouring the low-symmetry P6(3) model was identified in this study.
