The nanoparticles MgSb206 with trirutile-type structure were prepared by colloidal method using ethylanediamine (0.5 and 0.75 mL), following a calcination at 800 ℃. After, those powders were analyzed by x-ray obtaining a tetragonal structure with cell parameters, a = 4.64 A and c = 9.25 A and special group P42/mnm. Using a scanning electron microscopy were analyzed the powders calcined at 800 ℃, showing the formation of micro-plates, micro-rods, nanoparticles and morphology as rice grains. Employing a transmission electron microscopy, were found nanostructures hexagonal shaped with sizes of- 33.6 nm (0.5 mL) and 28.6 nm (0.75 mL). 展开更多
