Abstract: Twelve heteropolytungstate compounds containing group 2A elements KnZXW11O39·xH2O and KnZ'(XW11O39)2·XH2O(X = B, Si, As; Z = Mg, Ca; Z'= Sr, Ba) were synthesi-zed and characterized by elemental analysis, ion exchange, IR UV, XRD and TG-DTA me-thods.Their thermal stability were compared.

Key words: group 2A element, heteropolytun gstate, synthesis, thermal stability
