Platinized Titanium & Niobium Anode Dimensionally Stable Anode

The platinum clad niobium mesh is manufactured from a solid niobium sheet that has platinum of the specified thickness, mechanically clad to one or both surfaces.  The platinum clad niobium sheet is then "expanded" to form the mesh which has a stiffness that somewhat greater than aluminium window screen.  This leaves the inside edges of the mesh openings as exposed niobium which may be subject to anodization in some solutions, in this case the electrical "throwing power" of the electrode, (electrical conductivity with the solution), is maintained through the platinum cladding which maintains a liquid tight contact with the niobium substrate.

The niobium substrate is less rigid than the 0.030" expanded titanium and usually requires some type of framework to maintain the desired shape.  The niobium substrate is more conductive than titanium and the niobium under the platinum cladding is less likely to be affected by the solution.
