Abstract:In our previous article, we simulated the positions of Al atoms in zeolitic franework-After some Al atoms replace Si atoms, the charge compensatiug ions will be introduced. In zeolitefaujasite these ions are composed of Na and Ca ions. The interaction between the ions and frame-work are mainly of the electrostatic chararter. In this paper we calculate the electrostatic potentialdistribution of the basic structural framework of faujasite. We also simulated the positions of Na in dehydrated Na-faujasite based on the changes of the electr0static potential distribution whenthe Na atoms are added.
Keywords:Electrostatic potential Zeolite  Positions of cations  Computer simulation
