In the present work we report the synthesis of zeolite membrane on zirconium oxide and calcium silicate supports by secondary growth method. The effect of type of zeolite was evaluated on the formation of a homogeneous zeolite layer. Zirconia and calcium silicate disks of one centimeter of diameter were functionalized by (3-Mercaptopropyl)trimethoxysilane (MPS) and then they were rubbed with zeolite seeds. Two zeolite types were studied: LTA and MER. The functionalized substrates were submitted to hydrothermal treatment at 100°C, for 4 h and 175°C for 16h for LTA and MER zeolites, respectively. The products were characterized by SEM, XRD and IR techniques. The results indicated that the LTA zeolite led to formation of a homogeneous zeolite membrane on both substrates. While MER zeolite membrane only was obtained on the zirconia substrate. The nature of the substrate and the MPS had an important effect on the zeolite type growth on the substrate. The homogeneous zeolite membranes were soaked in a simulated body fluid in order to evaluate the formation of apatite layer this response could be associated to possible applications as bone filler.

The development of zeolitic coatings has attracted the attention because of the specific properties of these materials. The coating on different surface can contribute to solving the problems related to classical zeolite catalyst, such as powder crystals, microgranules and pellets. The zeolite coatings improve the mass transfer, low pressure and flow patterns. For these reasons in the present work, we studied the zeolite coating formation on glass sphere. The effect of physical and chemical modification of the substrate on zeolite coating formation was evaluated. The glass spheres were grinding using SiC paper and then they were soaked in a polyelectrolyte solution (PDDA, APS, or PEI). Afterward, the modified spheres were submitted to hydrothermal treatment using a batch composition 0.0257K2O: 0.0146 Na2O: 0.0146Al2O3: 0.0557SiO2: 0.829H2O at 448 K for 24 h. According to XRD results, the coating formed on the functionalized sphere corresponded to merlinoite and philipsite phases. It was found that the pretreatment of the spheres enhances the formation of a homogeneous zeolite coating with improved textural properties compared to the coating obtained on the glass sphere without previous treatment. These properties make these materials useful for adsorption and catalytic processes.
