Abstract
The article describes a method of obtaining porous tantalum at heat treatment in vacuum, from tantalum-cadmium coatings with a different ratio of tantalum and cadmium. The BET method estimated the surface area and showed that an increase in the specific surface area of the samples in terms of porous tantalum is 277.52 m2/g. A study was made of the ability of the obtained porous structure to accumulate charge and the processes occurring in porous tantalum during forming in an acid electrolyte.
