摘要

珍珠岩是一种无定形的硅酸铝，主要由SiO2和Al2O3组成。本研究尝试以珍珠岩为原料合成LTA型沸石。研究发现，以珍珠岩为原料的机械化学处理(研磨过程)导致其表面活化。结果表明，机械化学活化珍珠岩表面可优选合成lta型细沸石。

Synthesis and Evaluation of LTA Type Zeolite from Waste Perlite

Perlite is an amorphous aluminum silicate, mainly composed of SiO2 and Al2O3. In this study, we tried to synthesize LTA type zeolite from a perlite as a starting material. It was found that the mechano-chemical treatment (milling process) for perlite as a raw material resulted in the activation of its surface. As a result, fine LTA-type zeolites were preferentially synthesized for perlite with surface activated by mechano-chemical treatments.
