Zusammenfassung: | The invention discloses a device for granulating tantalum powder. The device comprises a sieve, a rotating frame which is rotated on a horizontal surface and is used for fixing the sieve and a receiving tray which is arranged below the sieve. The invention also discloses a method for manufacturing coagulated tantalum powder through granulation. The method comprises the following steps of: mixing the tantalum powder with liquid to form wet tantalum powder with the porosity of more than 40 percent; granulating to form separable coagulated wet tantalum powder with the porosity of at least 30 percent; drying the separable coagulated wet tantalum powder to obtain a pre-coagulated tantalum powder granulation body; and performing heat treatment on the pre-coagulated tantalum powder granulation body to obtain the coagulated tantalum powder. The tantalum powder produced by the method is high in physical performance and electrical performance and low in production cost. |
