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.
