NV -- (MARKET WIRE) -- 03/18/2005 -- Altair Nanotechnologies,
Inc. (NASDAQ: ALTI) announced today that two papers
have recently been published that illustrate the improved
durability of Altair's titanium dioxide nanoparticles,
when used as coatings on titanium metal or other high
performance metal alloys.
In testing conducted by Dr.
R. S. Lima and Dr. B. R. Marple at the National Research
Council of Canada, it was demonstrated that Altair's
nano-structured particles deliver superior strength
and durability, compared to traditional materials,
when used as a coating on surfaces. Altair nanosized
titanium dioxide materials act as crack arresters,
enhancing toughness which is a critical factor in
coatings applied to materials used in harsh environments.
Coating strength increased significantly as the porosity
of the Altair material was 2.5 times less than that
of conventionally applied traditional materials. Lima
and Marple also demonstrated that the coatings can
be applied with a lower cost process, high velocity
oxy-fuel, versus the traditional method of air plasma
spray, which may provide a significant cost improvement
for these tough, high strength coatings.
For the last two years, F.
W. Gartner based in Houston, Texas has been using
Altair's Titanium Dioxide nanomaterial to coat industrial
titanium ball valves which are used in applications
in the chemical, mining and petroleum industries.
Said Jimmy Walker, COO at F.W. Gartner, "We are
delighted with the results we have been achieving
with the Altair materials and the development of proprietary
coating processes (U. S. utility patent no.6835449).
Our customers are using a coating with twenty five
times the dry sand abrasion resistance and three times
the erosion resistance of conventional coatings."
Other applications for these
nanomaterial-based coatings are targeted, which include
coatings for rotor blades in gas turbine engines and
aircraft jet engines. These high performance coatings
are envisioned to reduce maintenance costs due to
their increased strength, and resistance to abrasion
"Altair is pleased with
the results of Drs. Lima and Marple's research, which
show improved durability of our Titania nano-materials"
commented Altair Nanotechnologies CEO Dr. Alan J.
Gotcher. "Our Titania nanotechnology has moved
into the product development stage and we are seeing
encouraging progress and product performance with
our market partners."
Copies of the two research
papers are available from the publisher at www.sciencedirect.com
and are entitled "From APS to HVOF spraying of
conventional and nanostructured titania feedstock
powders: a study on the enhancement of the mechanical
properties" and "Enhanced ductility in thermally
sprayed titania coating synthesized using a nanostructured
