Effect of Reaction Medium on Hydrothermal Stability of Mesostructured Silicate Material MCM-41
2003
For the example of sequential replacement of equivalent reagents, the effect of the reaction medium on the formation of mesostructured silicates of MCM-41 type is studied. It is shown that the reagents providing pH of the medium, solubility of the main interacting reagents can substantially affect the rates of hydrolysis and polymerization of silica, as well as enhance or weaken osmosis in the pores thus affecting the formation of the structure of a substance and finally its hydrothermal stability.
