摘　　要：以四乙基氢氧化铵为模板剂 ,采用水热法合成 β沸石。考察水热法合成 β沸石时体系中有机模板剂用量、水硅比、钠硅比及晶化时间等对合成的 β沸石相对结晶度的作用。样品的相对结晶度用X射线衍射仪分析。得出各种因素对合成Synthesis of zeolite beta by hydrothermal method was studied with tetraethylammonium hydroxide (TEA-OH) as an organic template. Effects of the amount of organic template, ratio of water to silica, sodium oxide to silica, and time of crystallization on relative crystallinity of zeolite beta were studied. Influences of these factors on crystal morphology of zeolite beta were characterized by using XRD. Results indicated the relation between these influencing factors and crystallinity of zeolite beta.
