摘　　要：首次以天然红辉沸石水热合成了 Y 型、P 型分子筛,以 IR 研究了水热合成体系中分子筛结构的演变及晶相分布规律。研究表明,在高 H_2O/Na_2O、低Ca^(2+)/Na^+体系中,主晶相为 Y 型分子筛,在低 H_2O/Na_2O、高 Ca^(2+)/Na^+体系中,主晶相为 P 型分子筛。Zeolites Y and P were synthesized hydrothermally from stellerite for the first time.The structure of zeolites synthesized from different hydrothermal conditions was characterized via IR spectra and XRD analysis.The results showed that the main crystal phase was zeolite Y in hydrothermal system with low Na_2O/H_2O and Ca^(2+)/Na^+ ratios and zeolite P is the main phase in hydrothermal system with the reverse condition.
