ABSTRACT:
A niobium suboxide powder comprising 100 to 600 ppm of magnesium is described. The niobium suboxide powder may (alternatively or in addition to 100 to 600 ppm of magnesium) further include 50 to 400 ppm of molybdenum and/or tungsten. The niobium suboxide powder is suitable for the production of: capacitors having an insulator layer of niobium pentoxide; capacitor anodes produced from the niobium suboxide powder; and corresponding capacitors.
