The early stage of phase separation in aluminoborosilicate glass for liquid crystal display substrates was investigated using a scanning electron microscope (SEM) and small‐angle X‐ray scattering measurement device (SAXS). The phase‐separated particles were detected with SAXS in samples in which no particle was observed with SEM. The particle diameter in an as‐formed sample was 2 nm. The relationship between the diameter and heat‐treatment time indicates that the phase separation proceeds by a diffusion‐controlled process. Based on the results of Fourier‐transform infrared spectroscopy, fast compositional change may occur in the early stage of phase separation.
