Study is made of the preparation of niobium suboxide by Mg reduction.Niobium Suboxide powder is prepared by mixture grinding-reduction roasting-acid washing for impurity removal-drying.Study is made through XRD and SEM on the product phase and microscopic morphology.Anode is made from niobium suboxide powder with the process similar to that of tantalum electrolytic capacitor.The anode electrical property is tested with anode testing method of electrolytic capacitor.The results showed that Mg reduction process is difficult to control with complex product phase,coarse particle size,simple particle shape.The resultant anode is characterized by low specific capacity,high ESR and high leakage current.
