There's no doubt
that no matter it is Artificial Graphite or Isostatic
Graphite, each of them belong to graphite. Perhaps you feel
graphite is far away from our day-to-day life and perform, you're producing a
massive error. Which is because graphite is quite critical and sensible right
here and there. Let’s share some understanding about graphite here today.
Let’s talk
anything regarding the morphology characteristic of graphite.
Generally
speaking, graphite is soft and black gray. What’s a lot more, it's with greasy
feeling. At the same time, it might pollute paper.
As for the
hardness of graphite, its hardness may be 1 to two. Nonetheless, along the
vertical path and together with the increasing of impurities, the hardness of
graphite could be elevated to 3 to 5. And also the particular gravity could be
from one particular point nine to two point three. The certain surface location
is concentrated at one to twenty square meters per gram. Under the situation of
isolation with oxygen, the melting point of graphite could be over 3 thousand
degrees. That is certainly to say that it is one from the most temperature
resistant minerals. As most of us know, graphite can not only conduct
electrical energy but also conduct heat.
There is no pure
graphite or High Purity
Graphite in nature. That is due to the fact graphite usually
includes Al2O3, FeO, SiO2, CaO, P2O5, CuO as well as other impurities. These
impurities usually occur inside the kind of quartz, pyrite, carbonate and also
other minerals. Furthermore, the impurities also can be included water,
asphalt, CO2, H2, N2, CH4 and other gas parts. Because of this, if we want the
analysis of graphite, except for the determination of carbon content, we also
should decide the contents of volatile and ash.
Speaking from
the major goal of graphite, let us talk about its conventional application.
Firstly,
graphite can be treated as a type of refractory material. Which is simply
because graphite and its products have properties of higher - strength, high
temperature resistance, graphite is mostly utilized to generate graphite
crucible within the metallurgical industry. What’s more, in steelmaking field,
graphite is usually utilized for the protection agent of steel ingot. In
addition, graphite may also be used for generating lining for metallurgical
furnace.
Secondly,
graphite may be employed as conductive material. It can be employed for
manufacturing electrode, carbon brush, carbon rod, carbon nanotubes, mercury
cathode in electrical sector, graphite gaskets, telephone components, coating
for TV picture tube and so on. Photovoltaic
Graphite is really a extremely good example.
Above all,
graphite plays an essential role in our daily life and perform. Let’s make very
good use of it!
