[ 1 ] - بررسی تجربی نانوساختارهای منگنز اکسیدها (MnO2 ، Mn2O3 ، Mn3O4) و خواص مغناطیسی آن‌ها

Manganese oxide nanoparticles were synthesized by sol-gel technique. Annealing in 250°C leading to produce Mn3O4 .Mn2O3 was obtained by increasing annealing temperature.Potassium permanganate and maleic acid were used to produce MnO2 at room temperature.The structural properties of manganese oxides were investigated by XRD spectrum and the average crystallite size were identified in the range o...
