We succeeded in preparing the MCM-41 sample, which possesses durability against water, through longer aging of a mixed solution of silica and surfactant in the temperature range from 308 to 413 K; the MCM-41 sample thus prepared was survived even after treating it in boiling water for one week. The properties of this sample were examined by XRD, 29Si CP MAS NMR, and FT-IR measurements to know the factor governing such prominent features. As a result, it was concluded that the surface crystallinity of the sample plays a pivotal role in protecting the sample against the attack of water.
