Platinum Plated Titanium
We have standard Platinum Plated
Titanium Lab Anodes in
stock and ready to ship.
The platinum plated
expanded titanium stock is produced by electroplating pure platinum onto
the expanded and flattened titanium substrate. This substrate
material is commonly available in thicknesses of 0.035" and 0.060".
In the case of custom fabricated electrode shapes the
titanium is fabricated to the customer's specifications and then
electroplated with the platinum to the specified thickness.
Due of the porous nature of the platinum deposit the
titanium substrate will come into contact with the solution, this may
cause anodization of the titanium substrate in which case the electrical
conductivity between the substrate and the solution will be maintained
by the platinum coating.
This type of electrode should not be used in a
solution such as hydrofluoric acid that could dissolve the titanium
Platinum Clad Niobium Mesh
Platinum Clad Niobium
The platinum clad niobium mesh is manufactured from a
solid niobium sheet that has platinum of the specified thickness,
(either 125 micro-inches or 250 micro-inches), 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
aluminum window screen. This leaves the inside edges of the
mesh openings as exposed niobium which may be subject to anodization in
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.
material is available as;
Platinum Clad Niobium
Sheets of either
type of material can be
fabricated per customer's specifications with frames and hanging tabs.
specifications for quote request
niobium mesh is manufactured in long strips that are 6 inches wide,
therefore, this material is most economical when ordered in 6 inch
widths with lengths in 6 inch
