An Introduction to Electrolytic Chromium Metal
High-purity Chromium Metal Flake and Powders
are used extensively to produce sputter targets
which are applied as thin film coatings in the
manufacture of a wide range of products, examples
of which include semiconductors, liquid crystal
displays, hard disk drives, low emissivity glass,
and car mirrors.
Standard Electrolytic Chromium Metal Flake is
an excellent feedstock for specialty melting applications,
or the production of MCrAly powders for which
low metallic trace elements are required. Standard
Electrolytic Metal Powder is supplied into the
welding industry as a alternative feedstock to
Aluminothermic Chromium Metal Powder for the production
of fluxes and cored wire; also as an alternative
to High-Purity Chromium Metal in the production
of sputter targets for less critical applications.
Electrolytic Chromium Metal Flake
This high-purity form of Chromium metal is produced
by deposition onto stainless steel anodes in the
electrolyte. By virtue of the fact that no pyro-metallurgy
nor alumino/silicothermic reduction is applied,
the resultant Chromium has extremely low levels
of unwanted trace elements. The physical form of the
cathode is broken flake, and, once degassed, offers
a high Chrome content, which can reach 99.99%
if required.
Electrolytic Chromium Metal Powder
Using the degassed cathode as the feedstock,
High purity Chromium Metal Powder is produced
at the joint venture facility in Newcastle, PA,
in a patented milling process that does not add
any significant contamination. The clean room
powder production facility adjoins the degassing
operation, thereby allowing for a fully integrated
production process, and tight control of the overall
throughput and quality of each batch produced.
