摘要
The following study is a continuation of our research on spontaneous synthesis of sodium zincophosphate sodalite by a simple grinding of the substrate components (e.g., ZnCl2 or Zn(NO3)2, Na2HPO4, Na2CO3). Rapid crystallization was used for the encapsulation of some substances (elemental sulphur, CdS, KBr, pyridine, hydroquinone) during sodalite structure formation. Attempts to increase the thermal stability of the resulting sodalite by adding some silicon or tin to the starting mixture brought about only a moderate improvement. The synthesis of potassium or ammonium derivatives of zincophosphate did not result in a sodalite structure.
