Perlite is an amorphous aluminum silicate, mainly composed of SiO2 and Al2O3. In this study, we tried to synthesize FAU 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, nano-sized FAU-type zeolites with higher Si/Al ratio were preferentially synthesized for perlite with surface activated by mechano-chemical treatments.
