TUNGSTEN CAPACITOR ANODE AND PROCESS FOR PRODUCTION THEREOF
摘要:
A capacitor anode including a tungsten sintered body having an average pore diameter of 0.3 μm or less; and a method for producing the anode. The method includes forming tungsten powder into a molded body having a density (Dg) of 8 g/cm3 or more and then sintering the molded body to a density (Ds) of at least 1.15 times the density (Dg) to form a tungsten sintered body having an average pore diameter of 0.3 μm or less.
