| description | The invention relates to tantalum powder, a preparation method thereof and an electrolytic capacitor anode made of the tantalum powder, in particular to tantalum powder of which the BET specific surface area is less than 0.530 m per g and the Fisher mean particle diameter is more than 3.00 mu m. The invention also relates to the method for preparing the tantalum powder, wherein the tantalum powder is prepared by using a reducing agent to reduce a tantalum compound. The method is characterized in that tantalum powder which is taken as a crystal seed is added during reduction and is grinded tantalum powder. |
