摘　　要：使用普通原料，用水热导向剂法制备出颗粒均匀的具有线团形貌特征的NaY分子筛，并利用XRD、FT—IR、SEM和TG-DTA等表征手段对其进行了表征。结果表明，线球形NaY分子筛颗粒由230nm左右的棱状小晶粒组成，不同于常规的NaY分子筛形貌，但热稳定性较差。Yarn spherical NaY molecular sieves were synthesized by using hydrotherm techniques with ordinary materials, and characterized by XRD, FT-IR, SEM and TG-DTA methods. It is shown that NaY zeolite spherical particles composed of small yarn crystal with particle size of around 230 nm, being different from conventional NaY zeolite morphology, but with a low thermal stability.
