| Abstract: | X-molecular sieve was synthesized from potassium feldspar occurring in Changbai Mt. by hydrothermal synthesis. The synthesizing procedures and the production capability were studied. The factor which influences the quality of the molecular sieve,mainly includes the mol ratios of H2O/Na2O and SiO2/Al2O3,the rotate speed during the reaction process and the aging of the gelatin mixture. 12 hours is the optimum crystallization time,and the absorbability of products reaches the state standards of chemical indust... |
