加晶種合成沸石的實驗，過去的研究主要偏重在加入晶種對結晶速率的影響，但晶種對晶核生成影響的研究仍少。本研究以方沸石為例來探討晶種含量對晶核生成的影響。
本研究以成份為Na2O．Al2O3．4SiO2的玻璃碎塊（20∼40目）為材料，加入0.5M氫氧化鈉溶液(固/液比為1/40)，在飽和蒸氣壓反應器中，210℃下反應一天，合成出方沸石晶種。再用玻璃粉末（＜100目）為材料，加入不同重量百分比的晶種，進行合成方沸石的實驗。實驗的條件為：150℃、180℃、210℃，飽和蒸氣壓，NaOH溶液濃度0.05M、0.1M、0.5M，固/液比1/40、1/80。並以粒徑來區分晶種和新生方沸石晶體。
研究結果顯示，方沸石的新生晶體，隨著晶種含量的增加而減少，且晶種粒徑因生長而增大；加入同量的晶種時，方沸石晶核的生成量隨溫度、NaOH溶液濃度和固/液比的降低而減少。本實驗在加入最少量的晶種（60wt%）而能完全抑制方沸石晶核作用的條件為150℃，飽和蒸氣壓，0.05M NaOH溶液，固/液比1/80。

Synthetic glass (<100 mesh) with the composition of Na2O．Al2O3．4SiO2 was used to testify the effect of seeding on the nucleation of analcime in NaOH solutions under hydrothermal conditions. Crystal seeds of 20,40,60,and 80 weight percent were added in the experiments. The experiment conditions are of vapar pressures; 150℃, 180℃, and 210℃; 0.05M, 0.1M, and 0.5M NaOH solutions; solid/solution ratios of 1/40 and 1/80.
Experimental results show that the nucleation of analcime decreases with increasing weight percent of crystal seeds, and the seeds grow to larger size after the experiments. The nucleation of analcime decreases with decreasing temperature, NaOH solution concentration, and solid/solution ratio as well when the same amount of seeds is added. . The best condition without nucleation of analcime is under 150℃, 0.5M NaOH solution, solid/solution ratio of 1/80, and 60wt% of seeds.
