Abstract

EXAFS of Si K-edge of α-quartz, silica and several silicate glasses is reported. The atomic distributions obtained using calculated phase shifts are discussed comparatively. The crystalline Si-O bond length which is common to silica is also common to the silicate glasses. The crystalline Si-O-Si bond angle is also retained in all the glasses but with some distortion.
