Description	The stability of amorphous aluminosilicate inorganic polymer systems (AIPs) with regard to the structural role of water molecules is discussed. Innovative approach to preparation of AIPs with amorphous and/or crystalline structure is introduced. It is shown that even small changes in the manufacture dramatically affect mechanical properties and the overall structural stability of AIPs. If the required quantity of water is admixed to the reaction mixture during the initial step of AIPs synthesis the resulting amorphous matrix undergoes extensive crystallization. If the amount of water is added to the reaction mixture during the last step of the preparation procedure, the AIP exhibits long-term stability. To find the structural reasons of the observed behavior a combination of traditional ssNMR, XRPD and TGA measurements were used. The applied experiments revealed that the structural stability of AIPs can be attributed to the tight binding of water molecules into the inorganic matrix.
