PROCESS FOR MANUFACTURING TANTALUM CAPACITORS.

摘要

A process for manufacturing tantalum capacitors in which microwave energy is used to sinter a tantalum powder compact in order to achieve higher surface area and improved dielectric strength. The process comprises cold pressing tantalum powder with organic binders and lubricants to form a porous compact. After removal of the organics, the tantalum compact is heated to 1300 DEG to 2000 DEG C. by applying microwave radiation. Said compact is then anodized to form a dielectric oxide layer and infiltrated with a conductive material such as MnO2. Wire leads are then attached to form a capacitor to said capacitor is hermetically packaged to form the finished product.
