Abstract
The use of crown ethers as templating agents in the system Ga2O3-P2O5-HF-H2O was investigated. The LTA-type gallophosphate could be obtained in the presence of the K+ 18-crown-6 ether complex and with aza-crown ethers (Kryptofix 22 and Kryptofix 222). These crown ethers are occluded in the structure (8 molecules per unit cell). The products were characterized by elemental analysis, SEM, XRD and solid-state NMR spectroscopy.
