説明
The intermediate phase (IP) between α and β phases of quartz, which has been reported previously by the present authors, was studied by a fine-beam X-ray Laue method. Then, one could find satellite reflections. The analysis shows that IP has a sinusoidal and displacive modulated structure which is characterized by 6 wave vectors q perpendicular to the a axes. The wave is transversal in the C-plane. The period Λ=q−1 of the modulation and the associated intensities increase as temperature decreases; i.e. Λ=172±10 Å on β side and 565±25 Å on α side. The satellites are likely owing to the optical mode of the displacive vibration of SiO4 tetrahedra.
