摘要: Quantitative data have been obtained on the surface structure of pyrogenic silica with a hydroxy group coating by solid-state 29Si NMR. Considerations presented include existence intraglobular groups, thermal stability silanediol population and possibility silanetriol groups. NMR spectra crystalline specimens polysilicic acid are also considered.
