Penelitian ini bertujuan untuk mengetahui pengaruh variasi asam (asam askorbat, asam sitrat dan asam maleat) sebagai chelating agent terhadap kristalinitas, ukuran kristal, konduktivitas dan morfologi dari material yang dihasilkan. Tahapan penelitian ini meliputi pencampuran reagen, evaporasi, pengeringan dan kalsinasi. Produk kalsinasi dikarakterisasi menggunakan XRD, multimeter dan SEM-EDS. Mineral penyusun elektrolit padat meliputi NaMnO 2 , MnO 2 MgO dan Na 2 O. Kristalinitas terendah dan konduktivitas tertinggi dimiliki oleh produk yang menggunakan asam askorbat sebagai chelating agent , dengan nilai konduktivitas 1,91 x 10 -4 Scm -1 ; ukuran kristal 26,09 nm dan ukuran aglomerasi 0,66 μm. Elektrolit padat NaMn 2-x Mg x O 4 yang dihasilkan untuk variasi chelating agent asam askorbat memiliki formula spinel NaMn 1,32 Mg 0,68 O 4 .}, issn = {2597-9914}, pages = {79--84} doi = {10.14710/jksa.18.3.79-84}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/18540} }
