There is certainly no doubt that irrespective of it's Artificial Graphite or Isostatic Graphite, each of them belong to graphite. Maybe you think graphite is far away from our daily life and perform, you're making a large error. That's simply because graphite is extremely important and practical here and there. Let’s share some expertise about graphite here these days.
Let’s speak
anything in regards to the morphology characteristic of graphite.
Usually
speaking, graphite is soft and black gray. What’s far more, it is with greasy
feeling. At the same time, it might pollute paper.
As for the
hardness of graphite, its hardness could be 1 to 2. Nonetheless, along the
vertical direction and with all the growing of impurities, the hardness of
graphite can be elevated to 3 to five. And the specific gravity could be from
one particular point nine to two point 3. The certain surface location is
concentrated at 1 to twenty square meters per gram. Below the situation of
isolation with oxygen, the melting point of graphite might be more than three
thousand degrees. That's to say that it really is a single of the most
temperature resistant minerals. As most of us know, graphite can not only
conduct electricity but in addition conduct heat.
There is no pure
graphite or High Purity
Graphite in nature. That's since graphite often consists of
Al2O3, FeO, SiO2, CaO, P2O5, CuO and also other impurities. These impurities
usually happen inside the kind of quartz, pyrite, carbonate as well as other
minerals. Additionally, the impurities also can be incorporated water, asphalt,
CO2, H2, N2, CH4 and other gas components. Because of this, if we require the evaluation
of graphite, except for the determination of carbon content, we also should
figure out the contents of volatile and ash.
Speaking on the
principal purpose of graphite, let us talk about its traditional application.
Firstly,
graphite can be treated as a kind of refractory material. That is since
graphite and its goods have properties of high - strength, high temperature
resistance, graphite is primarily used to create graphite crucible within the
metallurgical business. What’s far more, in steelmaking field, graphite is
generally utilized for the protection agent of steel ingot. In addition,
graphite also can be utilized for producing lining for metallurgical furnace.
Secondly,
graphite might be utilized as conductive material. It may be used for manufacturing
electrode, carbon brush, carbon rod, carbon nanotubes, mercury cathode in
electrical industry, graphite gaskets, telephone parts, coating for TV image
tube and so on. Photovoltaic
Graphite is actually a really good example.
Above all,
graphite plays an important role in our everyday life and operate. Let’s make
good use of it!
