• Usefulness of X-ray emission spectrometry was demonstrated in a study of the grinding reaction of the system of fine particle silica and basic zinc carbonate. Si<I>K</I>α bands of the ground mixtures shifted toward the lower energy side relative to that of the fine particle silica, whearas Si<I>K</I>β bands toward the opposite side. These band shifts were regarded as a measure of the reaction progress. The Si<I>K</I>β band shift was shown more distinctly than the <I>K</I>α band shift and explained as come from a decrease in the <I>s</I>-character of the bond caused by the chemical bonding of the zinc atom with the fine particle silica. The <I>K</I>β band shift was also correlated with the destabilization energy relative to the fine particle silica after C. G. Dodd and G. L. Glen. The band shifts indicated that the final product of this grinding reaction was amorphous zinc silicate-like compound. The correspondence of the X-ray band shifts with the infrared spectral shifts was also shown.
