In the last three months we studied the phase composition of the fly ash in order to better understand the important parameters in the zeolite formation process using fly ash. In addition, since the zeolites exist in powder form, for practical applications, some ways of binding them into a piece of material is necessary. For that purpose, we began exploring ways of forming porous materials using fly ash. It was found that mixing fly ash, phosphoric acid, and calcium oxide can generate a porous material with good integrity. Meanwhile, the research on forming mesoporous materials from fly ash continued. Some results on the formation of double lamellar phase was found during the study
