Abstract

PHYSICAL C HARACTERISTIC OF ALUMI NOSICA TE GEOPOLYMER BASED ON RICE HUSK SILICA FO R FA ST I ONIC C ONDUCTOR A PPLICATIO N. The study aims to investigate the effect of calcination temperatures on the phase formation and electrical properties of aluminosilicate geopolymer prepared from rice husk silica and sodium aluminate. The samples were calcined at temperature from 150 to 550 C, the development of structures was characterized using xray difraction (XRD) and the electrical properties were measured by LCR meter. The result obtained indicated the significant role of calcining temperature on phase transformation of boehmite and quartz into aluminosilicate geopolymer, in which at calcining temperatures from 450 to 550 oC, and the samples were dominated by semicrystal to amorphous phase which indicated that the aluminosilicate geoplymer has been formed. The presence of aluminosilicate geopolymer resulted in increased ionic electrical conductivity and dielectric loss factor as well as decrease dielectric constant. Ionic electrical conductivity of the calcined sample at 450 oC is 4.49x10-5 S/cm at frequancy of 5x106 Hz, and XRD analysis demonstrated that the main structure is phase of semicrystal aluminosilicate geopolymer. Based on these character, the sample was considered is very suitable used to the fast ionic conductor materials.
