| Abstract(in English) | Calcium zeolite type A (CaNaAlSi_2O_7) called soda melilite with the molar ratio of CaO:Al_2O_3:Na_2O:SiO_2 is 1:1:2:8 was prepared by the sol-gel process and calcined at 300℃ for 1 h. The CaNaAlSi_2O_7 catalysts have the N_2 adsorption-desorption isotherms and good electrical properties. The specific surface area, total pore volume, and average pore diameter are 55.15 m^2/g, 0.5127, and 371.90 A°, respectively by Braunauer Emmett Teller (BET). The dielectric constant, electrical conductivity, and loss tangent are 46.5785, 5.2360x10^<-3> (Ω.m)^<-1>, and 2.7540, measured at room temperature and at 1000 kHz (1MHz), respectively. The transmission electron microscopy (TEM) images of the samples show that good dispersion and uniform particles with an average diameter of about 0.5 nm are prepared. |
