The applications and the future of isostatic graphite

1
What's the research direction of isostatic
graphite (also called isomolded graphite) in
china? the project that each competitor shoulds
consider.i think the isostatic graphite products
should meet demands of the china
graphitemarket. isostatic graphite is widely used
in solar cell?semiconductor chip and photovoltaic
industrydue to the features of
high-strength,high density and isotropic
homogeneity,the graphite products
is well-distributed when they are used.and at the
same time the nice thermal shock performance
which can prolong the life cycle of the
equipment and utensils.so they are used in
semiconductor and photovoltaic industry like
graphite crucible,graphite heating elements,guide
cylinder and so on.isostatic graphite is the
Boutique of graphite materials,it has excellent
properties that other gaphite materials don't
have,which is the first chooice of
polycrystalline silicon,monocrystalline silicon
used heat-resisting material.recent 10
years,solar photovoltaic industry has developed
rapidly,the average rate of increase is
41.3.through in 2009 economic crisis has
occured,solar photovoltaic industry of the world
still increased speed at above 30.
after The Copenhagen climate BBS,it has larger
space development.it will restorative 50-60
in the future of 2010.and china as the largest
country of solar photovoltaic production,which
will share 70 of the market,High grade graphite
material consumes 5000 tons in 2009,in the future
the demands of isostatic graphite will increase
at the speed of 2530.The applications of
isostatic graphite in the solar photovoltaic
industry will be the best chance to develop for
isostatic graphite Manufacturing enterprises.at
present,The single crystal size of isostatic
graphite has Big
2
normalized,in 2010-2011 the 20 inches has
replaced the 18 inches and will be
more big.polycrystalline silicon will be
Scaling-up development,the direction is high-end
products.Upsizing and High specification of the
solar photovoltaic industry requires the gaphite
bigger size,Higher strength,Higher
purity. isostatic graphite is used in EDM
Machining and better than copper electrode.The
proportion of graphite is 1/5 of the copper,the
weight of the same volume of graphite is
relatively light for 5 times of copper,which is
easy to make large die mold.the graphite
processing speed is generally 3-5 times faster
than ordinary metals,which can reduce the tool
wear and electrode consumption.Graphite is high
melting point and not easy transformed,so don't
have to worry about deformation and damage of
components of high processing.after the
completion of Graphite in processing,the
polishing processing generally don't have to be
which will reduce the error and shorten the
production cycle.along with reasonable processing
parameters,the processing speed of graphite
electrode will be low dissipation factor and to
be the zero loss,so it can be theoretical zero
loss,it will reduce the number of repeated
electrode processing.Because of graphite material
has the advantage of copper material,at
present,many mold factories are converted into
graphite Manufacturers,so as to shorten the
delivery time of products and enhance
competitiveness in the market.the ratio of
graphite and copper is 82 in EDM processing of
Europe,and the Chinese market is 37,along with
the rise in copper prices and technological
progress,the proportion of using graphite will
continue to rise,therefore,the development space
of graphite used in edm industry will be
great.During the period of "15" ,mold markets
demand is very prosperous,and the foreground is
very good.Mould Products will has the feature
of precision,large-scale,complexity,long life.so
that will require the graphite Upsizing On the
specification,particle size refined and strong
capability of anti-crack. High temperature gas
cooled reactor is structured of isostatic
graphite.High temperature gas cooled reactor is
In the international leading level which is
listed in national major projects.nuclear power
station needs 1200 tons of isostatic graphite
material,that's 15 a total investment of cost of
the demonstration reactor.for the healthy
development of nuclear power enterprise of
china,Many domestic experts are calling for
domestic enterprises to participate in the
research and development of nuclear
graphite.Domestic nuclear graphite materials
expert xushijiang said"gaphite is the critical
material of High temperature gas cooled reacto
and Nuclear graphite is also can prevent the
proliferation,Although it can be Imported,once
the international situation changes, it will be
interrupted at any time.we Must solve the problem
of the localization of nuclear graphite,so that
we can develop independently the industry of High
temperature gas cooled reactor."XRD Graphite
Manufacturing Co.,Ltd supplied 40 tons isostatic
graphite material to the
3
Tsinghua university nuclear power school at first
in 2011.As requests that's completed
on schedule,quality,price for the supply of
nuclear graphite materials. Product main
technical indicators has exceeded expectations,it
successfully completed the nuclear graphite trial
production tasks,which step well in the process
of localization of nuclear graphite.the main
difference between nuclear graphite and regular
Engineering graphite,is pure and resistance to
radiation damage.The next step is to develop
irradiation test,The quality requirements of cold
condition of nuclear graphite is Specifications
of large-scale,stable quality,good thermal
stability,low thermal expansion
coefficient,Nuclear pure (high purity 50 parts
per million).isostatic graphite is New graphite
material and the competitive products of graphite
materials,due to favorable properties of
isostatic graphite,it must be closely
interrelated with advanced technology and top
technology of national defense and will be one of
the most valuable new materials. With the
economic development,the market capacity of
isostatic graphite has increased in domestic and
international,huge potential for
development.that's why so many companies are busy
to produce the isostatic graphite
materials.Competition will be inevitably enter
the white-hot state,include the competitors from
outside the countries.In the fierce market
competition,the way out of isostatic graphite
Machining companies of China is developing new
generation of products,following the development
trend of photovoltaic industry,machinery
manufacturing,nuclear power industry,providing
better service of the development of chinese
national economy. Article From
