SINTESIS DAN KARAKTERISASI NANOPARTIKEL MAGNESIA STABILIZED ZIRCONIA (MSZ) RENDAH TENORM BERBASIS ZIRKONIUM OKSIKLORIDA MENGGUNAKAN TEMPLAT PEG-6000
This study aims to synthesize low TENORM Magnesium Stabilized Zirconia (MSZ) nanoparticles based on zirconium oxychloride using polyethylene glycol (PEG-6000) as a template, and to study the effect of variations in the mass ratio of PEG-6000 and calcination temperature on the characteristics of the resulting material. The addition of magnesium as a dopant serves to stabilize the zirconia crystal phase, specifically maintaining the tetragonal-cubic phase at room temperature through the substitution mechanism of Mg²⁺ ions into the ZrO₂ lattice which produces oxygen vacancies, thereby increasing the structural stability and mechanical properties of the material. The synthesis of MSZ was carried out through the process of precipitation, purification, addition of magnesium dopant, and calcination at temperatures of 900 °C and 1000 °C with variations in the mass ratio of PEG-6000 of 1:0, 1:1, and 1:3. The resulting MSZ product was characterized using X-ray diffraction (XRD), X-ray fluorescence (XRF), Fourier transform infrared (FTIR), scanning electron microscopy (SEM), and alpha-beta spectrometer to evaluate the crystal structure, elemental composition, functional groups, particle morphology, and radioactivity levels. The XRD results showed that the formation of magnesium-stabilized zirconia was characterized by the dominance of the tetragonal–cubic ZrO₂ phase and the appearance of MgO–ZrO₂ compounds, with increasing crystallinity at a calcination temperature of 1000 °C. SEM analysis showed that the addition of PEG-6000 played a role in controlling particle growth and reducing the agglomeration rate, resulting in an average particle size below 100 nm, especially at the PEG-6000 1:3 variation. Based on the results of XRF and alpha-beta spectrometer, the ThO₂ and UO₂ content and radioactive activity in MSZ decreased compared to the initial raw material, which indicates the successful synthesis of magnesium-stabilized zirconia material with low TENORM characteristics. Thus, variations in the PEG-6000 ratio and calcination temperature significantly affect the crystal structure, morphology, and radiological characteristics of MSZ nanoparticles.
