以沸石粉为原料，在150 °C水热热压条件下，成功地合成了高密度、半透明的块体X型沸石。通过加入少量蒸馏水或1 mol/L NaOH溶液实现致密化。观察到致密的块状陶瓷体的增强的钠离子传导。所获得的离子电导率超过0.001S/cm，并且与应用于电化学装置（例如电池和化学传感器）的实际固体电解质的离子电导率相当。
Highly dense bulk zeolite X with translucency was successfully fabricated by hydrothermal hot-pressing of zeolite powder at 150 °C. Densification was achieved by addition of a small amount of distilled water or a 1 mol/L NaOH solution. Enhanced sodium ion conduction was observed for the densified bulk ceramic bodies. The ion conductivities obtained were beyond 0.001 S/cm, and are comparable to those of practical solid electrolytes applied in electrochemical devices such as batteries and chemical sensors.
