Provided are manufacturing methods of a magnesium-vanadium composite oxide nanoparticle that make it possible to manufacture a composite oxide of several tens of nanometers in size containing two kinds of metals, and also to accurately design and manufacture a product material having a desired ratio between the metals, and a magnesium-vanadium composite oxide nanoparticle manufactured by the manufacturing methods. In the manufacturing method, a solution containing a magnesium salt and a vanadium salt is prepared. An organic polymer having nano-sized pores is dipped in the prepared solution, and is then heated until the organic polymer is calcined, thereby manufacturing a magnesium-vanadium composite oxide nanoparticle.

A method of manufacturing complex oxide nano particles includes preparing a mixed solution including at least one metal salt selected from the group consisting of aluminum salt, manganese salt and barium salt, impregnating an organic polymer having nano-sized pores with the mixed solution, and calcining the organic polymer impregnated with the mixed solution. Accordingly, complex oxides with particle sizes on the nanoscale can be prepared, and the kind and composition ratio of metal elements contained in the complex oxides can be facilitated. Also, a multilayer ceramic capacitor including the complex metal oxides manufactured by this method can ensure a super slim profile and high capacity.
