PURPOSE:To obtain granules for an electrolytic capacitor having superior electrical characteristics by mixing titanium powder and/or titanium hydroxide powder with aluminum powder, heating and alloying the powdery mixture in vacuum or an inert gas to form lumps, and crushing a part of the lumps on a mesh. CONSTITUTION:Titanium powder and/or titanium hydroxide powder of <=3mum average particle size is mixed with aluminum powder of <=4mum average particle size. The powdery mixture is heat-treated at about 650 deg.C in vacuum or an inert gas to form lumps by partial alloying and bonding. The lumps and nylon balls are put on a sieve of about 0.5mm. mesh. By vibrating the sieve, the lumps are crushed with the balls and classified through the sieve.
