Telah dilakukan penelitian tentang sintesis magnesium oksida (MgO) menggunakan metode presipitasi. Nanopartikel MgO disintesis dengan memvariasikan temperature sintering yaitu 400 C, 500 C, 600 C, dan 700 C dengan massa PEG-6000 2 g. Struktur kristal, ukuran kristal, morfologi permukaan, dan distribusi diameter partikel dari nanopartikel ini dikarakterisasi menggunakan X-Ray Diffraction (XRD) dan Scanning Electron Microscope (SEM). Dari hasil analisis pola difraksi sinar-X ditunjukkan bahwa struktur kristal MgO berbentuk kubik dan morfologi permukaan MgO berbentuk bulat (spherical). Ukuran kristal semua sampel berkisar antara 27,36 – 45,57 nm dan ukuran partikel semua sampel berkisar antara 30,41 – 95,92 nm. Hasil SEM menunjukkan semakin tinggi temperatur sinteringnya maka morfologi permukaan MgO semakin homogen.
