CVMR®'s processes and technologies have many applications that serve a variety of industries, in
addition to the metal refining industry.
CVMR®’s processes produce a range of metal powders in varied forms and morphologies. They can also
produce solid metals with a nano-crystal structure and can manufacture metal foams and ultra-pure powders
as
dense products, or as filamentary products, to meet various specifications.
Samples of CVMR®’s Nickel Powders are:
By varying the process parameters at the end of the refining, a wide range of metal forms are created,
such
as:
- The production of pure metal powders and metal foams, used for batteries, catalysts, capacitors, or
for
alloys, which require ultra-pure metals.
- Production of graphene and graphite for use in batteries, net shapes, desalination plants,
construction
materials and other industrial applications
- The application of pure metal coatings on a wide range of substrates, including non-metallic materials
such as powders, fibres, resins, composites, polymers, ceramics, and metallic coatings inside porous
substrates.
- The production of solid metal net shapes and mould inserts directly on the master with perfect
replication. These tool inserts require no polishing.
- The manufacture of seamless net shapes, such as uniformly deformable cans (“HIP cans”) used for
isostatic pressing.
- The production of nickel moulds made for the manufacture of plastic light-wave guides, for hand-held
computer touch screens. These uses etched silicon wafers as the master forms.
- The manufacture of thin nickel parts as fuel cell focusing devices for NASA’s deep space program.
CVMR®’s metallic vapour infiltrates into cavities and pores of various substrates to coat their inner
surface completely. This can provide strength, conductivity, mass and protective layers for the
substrates.
The CVMR® process can decompose the metalorganic gases in layers of metals with different
characteristics, simply by varying the gas compositions, in order to produce layered metals, or alloys,
with
varying metal mixes as part of one continuous piece. For example, hardness, ductility, and the percentages
of various metals used in an alloy, can be varied from one end of the metal alloy, to the other.
The growth of the pure metals by thermal decomposition ensures that every feature of a master form is
replicated perfectly atom by atom. The CVMR® process is, therefore, excellent for optical parts by
reproducing mirror finishes exactly. For example, perfect replicas of bank-note masters reproduced in the
nickel printing plates made for the U.S. Treasury Department, Bureau of Engraving & Printing. (The first
time in the history of U.S. Treasury Department dollar plates were made outside the USA).
Telecommunication devices are moulded precisely with the assistance of mould tool inserts made by the
CVMR® process. This enables plastic parts manufacturers to produce accurate parts with significantly
high tolerances. In the bio-technology industry, medical instruments such as tipping tools, are made with CVMR® mould
inserts.
The CVMR® process applies well to the metal coating of a wide range of materials. Any substrate can be
metal-coated by this gaseous process, provided that the material is stable at a temperature of 175°C and
does not off-gas. This enables CVMR® to apply coatings to metal and non-metal powders, such as
ceramics,
polyamide, silicon, resins, fibres, carbon whiskers and porous materials.
