Abstract
The synthesized Mg-bearing silica gel was investigated as a model for a comet nucleus. The samples were compressed under shock compression of 15, 20 and 25 GPa. The samples were examined by XRD, FTIR and TG–DTA. The compressed sample showed that the crystallization occurred by shock compression of 15 GPa. The crystallization of the sample was affected by shock temperature, but it is also supposed that the compression has a considerable influence on the crystallization.
