摘　　要：杂原子Ｐｂ同晶取代Ｓｉ－ＺＳＭ－１２中的部分Ｓｉ及其鉴定赵修松，王清遐，李宏愿（中国科学院大连化学物理研究所，大连１１６０２３）关键词Ｐｈ－ＺＳＭ－１２，合成，表征ＺＳＭ－１２属丝光沸石类，具有一维线性非交叉孔道（０．５７×０．６１ｎｍ）［１，２］，...eolite of Pb-ZSM-12 has been synthesized from the reactant mixture of Na2O-PbSO4-SiO2-MTEAI-H2O at 428-448 K in an autoclave.XRD results associated with IR study of the lattice vibrations indicated that highly crystalline materials with the ZSM-12 structure were obtained. IR, DTA studies along with XPS measurements showed that Pb is in tetrahedral positions.
