Abstract: X molecular sieve was synthesized from potash feldspar ores by baking and hydrothermal synthesizing procedures. The optimal technological parameters were determined by means of quadrature experiment. The properties of the synthesis powder such as XRD, crystal constants, SEM, DTA, chemical composition, SiO2/Al2O3 are similar to those of the ideal 13X moleclar sieve. And its absorbability comes up to the state standards of chemical industry of China.

Key words: potash feldspar, 13X molecular sieves, synthesis
