Four new types of microporous beryllophosphates were hydrothermally synthesized using BeO - P_2O_5- R - MCl (or MCl_2) - H_20, R being HMDA (1, b-hexanediamine), EDA (ethylenediamine), or TBAOH (tetrabutytamine hydrox... Four new types of microporous beryllophosphates were hydrothermally synthesized using BeO - P_2O_5- R - MCl (or MCl_2) - H_20, R being HMDA (1, b-hexanediamine), EDA (ethylenediamine), or TBAOH (tetrabutytamine hydroxide), M alkali or alkali earth cation. By means of X-ray diffraction patterns (XRD), infrared (IR), TG-DT and elemental analyses we show that the crystalline beryllopbospbates have novel, unique framework structures, composed from basic units of tetrahedral P0_4 and Be0_4. These materials exhibit zeolite-like adsorption and ion-exchange properties. 展开更多
