Abstract

Zirconia (ZrO2) is one of the refractory ceramic materials that have applications in several fields. The aim of this study was to synthesis ZrO2 from natural zircon sand collected from Kereng Pangi, Central Kalimantan with a variation of pH deposition using alkali fusion co-precipitation method. The synthesis procedure of ZrO2 was began with the preparation process involved magnetic separation, milling, and leaching with HCl. Furthermore, the alkali fusion process was performed using KOH solution and heated in an electrical furnace at 700ο C for 3 h, whereas co-precipitation process was carried out using a filtrate mixed with the NH4OH solution to reach a pH variation between 3-11 and then precipitated for 12 h. The precipitates were dried in an oven and then calcined at 800oC for 3 h. The structure of synthesized ZrO2 was characterized using XRD, and the particle sizes were measured using particle size analyzer (PSA). The XRD analysis shows that the identified phase of zirconia powder is tetragonal with crystal sizes in nanometer order. Result of PSA measurement revealed that the crystal size decreased in the range pH of 3-7 but increased in the range pH of 7-11. The biggest powder particle size could be achieved at 260 nm with pH 7, whereas the smallest size was at 143 nm occurred at pH 3.
