As an unit of tantalum anode, tantalum wire plays an important role in tantalum capacitor. Its microstructures and textures can affect tantalum wire's quality and even capacitor's characteristic. More rigorous requisition will be needed for tantalum wire's quality and low cost with thinning of tantalum wire. So it is necessary to study the stability of tantalum wire production technique. The magnitude and homogenization of recrystallization can directly affect tantalum wire's property for annealing being th...
