An order parameter treatment of the phase transitions in leucite, KA1Si206, at approximately 950 and 920 K: Ia3d(cubic)--\* I41/acd(tetragonal) --,I41/a(tetragonal) is presented in terms of Landau theory and induced representation theory. The AI-Si order with decreasing temperature is taken as the p
## Abstract Pressureβinduced amorphization has been observed in two zeolites, natrolite Na~2~Al~2~Si~3~O~10~ Β· 2H~2~O and leucite KAlSi~2~O~6~. Using Raman microprobe, amorphized samples were analysed __in situ__ at high pressures at compression in methanolβethanol medium in diamond anvil cell and
