摘要：

Al-27 and P-31 nuclear magnetic resonance studies have been carried out in order to investigate structural changes in connection with the thermally induced transformation of VPI-5 to AlPO4-8 as well as a structure indication of AlPO4-8 itself. Dramatic changes in the spectral pattern were observed during the transformation. Hydrated AlPO4-8 apparently consists of three different environments in the ratio of 1:2:6.
