Faujasite zeolite was synthesized on the basis of the native zeolite of Nakhchivan, and its physicochemical properties were studied. The zeolitic tuffs of Nakhchivan (Kyukyuchaiskoe field) served as the native sample. It was determined that faujasite exists under a wide range of conditions; the optimal conditions of its hydrothermal synthesis were found to be temperature 100 – 200°C, thermal solution concentration 10 – 15% Ca(OH)₂, and process time 50 h.

基于纳希切万原生矿物的八面沸石的合成与研究

以纳希切万的天然沸石为基础合成八面沸石，并对其理化性质进行了研究。Nakhchivan（Kyukyuchaiskoe油田）的沸石凝灰岩为天然样品。可以确定八面沸石存在的条件广泛。发现其水热合成的最佳条件是温度100 – 200°C，热溶液浓度10 – 15％Ca（OH）₂，处理时间50 h。
