Abstract
31P MAS NMR has been used to determine 31P chemical shift tensors of crystalline silicon phosphates. The chemical shift data of five polymorphs of SiP 2O 7 (hexagonal, tetragonal, cubic and two monoclinic forms) are presented besides those of Si 3(PO 4) 4. Results of 31P 2D exchange NMR on a phase mixture of different silicon diphosphates are shown. This novel approach allows an unambiguous identification of the various phases even in multicomponent mixtures as occurring in ceramics.
