SILICA HYDROGEL AND SILICA

摘要

PROBLEM TO BE SOLVED: To provide silica having a new structure which is not conventionally known from the viewpoint of microstructures and to provide a silica hydrogel used for producing the above silica. SOLUTION: The silica hydrogel produced shows such properties that, when the gel is dried without hydrothermal treatment and measured by wide-angle X-ray scattering, the spectral pattern has a peak in each of two regions of a q-value satisfying 0.7≤q≤1.3 and 1.3
