摘要：

The small pore silicoaluminophosphate SAPO-43 has been synthesized as a pure phase, producing crystals of very high quality. Detailed physical and chemical characterization indicates that the structure of this material is not stable after the removal of the template during calcination. Chemical analysis and solid-state n.m.r. studies confirm that silicon substitutes exclusively into the phosphorus site, The high level of silicon incorporation could result in a degree of P/Si ordering within the phosphorus site of the framework. Assuming short-range ordering of the order of the unit cell dimensions, only one model is apparently feasible. (C) Elsevier Science Inc. 1996
