Procedure

We found that P type zeolite can be synthesized by mixing sodium silicate or active silicic acid gel, sodium aluminate and sodium hydroxide under the following molar ratio conditions to form a gel of sodium alumino-silicate, homogenizing this gel and effecting crystallization at a temperature of 85° to 200° C. under atmospheric pressure or under hydrothermal conditions. P type Zeolite-Forming Ratios:
