Abstract:
PURPOSE: A magneli phase titanium oxide with a high specific surface area is provided to secure 35 wt% or more of a metal loading amount due to the high specific surface area and have excellent electric conductivity, high-voltage durability, and a high corrosive resistance under an oxygen atmosphere. CONSTITUTION: A magneli phase titanium oxide has a specific surface area in the range of 3-50m^2/g. The titanium oxide contains 80 wt% or more of Ti4O7 and Ti5O9. The titanium oxide further contains non-stoichiometric titanium oxide of TikO2k-(1+2l)(k is a natural number, wherein 4
