Types:Medium Cardon Graphite.
Specifications:The particle size ranges form
**0?m***0?m(**0mesh**5mesh),and the carbon content ranges from *0
to *1%. We have five principal products: **5 mesh,**0 mesh,+
*0mesh,***0 mesh and ***0 mesh.
Advantages:Perfect crystallization, large
flake,good flexibility, excellent chemical and physical
properties,superior conductivity,self-lubricity and resistance to
temperature,corrosion and hot shock,and much more. To the *0 mesh
graphite, expansion ratio is **0 or more.
Usage:Large flake graphite is widely used as an
essential nonmetalic mineral in almost all industries.It can be
used as high-quality refractory material or coatings in
metallurgical industry,black lead in light industry,carbon brush in
electronics industry,electrode in battery industry and catalyst in
chemical fertilizer industry, to name just a few. After being deep
processed,crystalline flake graphite can be used to produce TV tube
coatings,graphite friction reducing additives and many other
high-tech products. Our product is one of the most suitalbe
graphite to make expandable graphite.
What Is Graphite and What Makes
It So Special?
Graphite and Diamonds are the
only 2 naturally formed polymers of Carbon. The essential
difference between the two is simply
structure�Graphite is 2 dimensional where
as Diamonds are 3. Graphite�s unique combination of planar
structure, relatively pure carbon composition, and metamorphic
origin give it� valuable characteristics such as;� being an
excellent conductor of heat and electricity, having the highest
natural strength and stiffness of any material and even the ability
to maintain its strength and stability to temperatures in excess of
3,**0OC.
It is also very resistant to chemical attack. At the same time, it
is one of the lightest of all reinforcing agents and has high
natural lubricity. These powerful set of properties offer an
incredible range of applications the commercial world has yet to
see.

�The
U.S., China and the EU classify Graphite as a critical strategic
material�

From its longstanding and
unassuming place as the�lead�in
pencils, recent discoveries, consumer demands and market readiness
have this simple elemental form of Carbon now poised to
revolutionize the way we live. The U.S., who is a **0% importer of
graphite, has joined China and the European Union in classifying
Graphite as a critical strategic material. Graphite demands are
exploding as valuable and broad applications are being researched
and developed daily from consumer electronics, green energy,
medical, mining and even military applications. Imagine a cell
phone so thin and flexible that you can roll it up and put it in
your pocket, or printable electronics, or even an invisible cloak.
This is the future of Graphite with some applications already in
commercial production.
Graphite�s
Traditional Demand
When one mentions Graphite,
most people likely think of a pencil.� An equal number would
probably be surprised to know that pencils only account for about
*4% of the world�s Graphite demand.� Like
Vanadium, traditional demand for graphite today is largely tied to
the steel industry, which accounts for about *2% of total graphite
demand.�

Graphite and
Steel
Since Graphite is an excellent
conductor of heat; able to maintain its strength and stability to
temperatures in excess of 3,**0�C and is very resistant to
chemical attack, it is ideal for various aspects of steel
making;
�
- as a liner for ladles and
crucibles (used to hold molten metal)
- as a component in bricks, which
line furnaces (�refractories�)
- as an agent to increase the
carbon content (strength) of steel
- in graphite electrodes, which
are used exclusively in steel
mills�electric
arc furnaces to help melt scrap metal
- �
Industrial demand for graphite
has been growing at about *5% per annum for most of this decade due
to the ongoing industrialization in China, India and other emerging
economies.
Graphite and Automotive
Engineering
Because graphite is one of the
lightest of all reinforcing agents and has high natural lubricity,
it plays an integral role in automobiles. Graphite is a crucial
material in cylinder heads, gaskets, clutch materials, exhaust
systems and motors.
Graphite enabled the world to
replace asbestos as the main component in disk brake pads and
linings, while providing another benefit - quiet brakes. Due to
Graphite�s natural lubricity, it resists
noise; so squeaky breaks have been greatly
reduced.
Increasing Graphite Demands
from Growing Market Applications
Graphite in Lithium Ion
Batteries
Lithium (Li) ion batteries are
smaller, lighter and more powerful than traditional batteries. They
also have no memory effect and a very low rate of discharge when
not in use. As a result, most portable consumer devices such as
laptops, cell phones, MP3 players and digital cameras use Li ion
batteries and they have now moved into power tools as
well.
