Structural stability of aluminosilicate inorganic polymers: influence of preparation procedure

Popis výsledku v původním jazyce

The stability of amorphous aluminosilicate inorganic polymer (AIP) systems with regard to the structural role of water molecules incorporated in inorganic matrix is discussed. Innovative approach to preparation of amorphous AIP systems with identical chemical composition but differing in structural and mechanical behavior is introduced. It is shown that even small changes in the manufacture dramatically affect mechanical properties and the overall structural stability of AIP systems. If the required quantity of water is admixed to the reaction mixture during the initial step of AIPs synthesis the resulting amorphous aluminosilicate matrix undergoes extensive crystallization (zeolitization). On the other hand, if the amount of water is added to the reaction mixture during the last step of the preparation procedure, the inorganic matrix exhibits long-term stability without any structural defects. To find the structural reasons of the observed behavior a combination of traditional solid s
