What Are The Applications Of High Purity Graphite

(What Are The Applications Of High Purity Graphite)

If the 20th century were the age of silicon, carbon would be one of the
fastest-growing and most widely used materials of the 21st century. Lithium
battery anode materials, graphene materials, isotropic nuclear graphite,
synthetic diamond, flexible graphite, and other advanced carbon are playing an
increasingly important role in people's life, production, and military
affairs.

High purity graphite refers to graphite powder containing more than 99.9%
carbon, high purity graphite of high carbon content, such high purity graphite
has good conductivity, lubrication, high-temperature resistance, wear
resistance, etc.

The use of high purity graphite in the field of industrial production has
excellent performance. High purity graphite is used in conductive, lubrication,
metallurgy, and other industrial production fields. High purity graphite
production, from the beginning of the raw materials, should be strictly
controlled the content of impurities, choose low ash raw materials, and in the
production process to prevent the increase of pollutants as far as possible.
However, the reduction of contaminants to the degree required is primarily in
the graphite chemical sequence. Graphitization occurs at high temperatures,
where the oxides of many impurity elements will decompose and evaporate. The
higher the graphitization temperature is, the more impurities are discharged,
the higher the purity of the high purity graphite products are produced. The
high purity graphite is used to make use of its excellent conductivity,
lubrication, high-temperature resistance, etc.

High purity graphite is a high purity, fewer impurities. This depends on the
complete production process and production equipment.

Special properties of graphite

1.High-temperature resistance: Graphite melting point is 3850± 50℃, the
boiling point is 4250℃, even after ultra-high temperature arc burning, weight
loss is minimal, the thermal expansion coefficient is insignificant. With the
increase of temperature, the strength of graphite increases At 2000℃, the power
of graphite is doubled.

2.Conductivity, thermal conductivity: The conductivity of graphite than the
general non – metallic ore 100 times higher. The thermal conductivity exceeds
that of steel, iron, lead, and other metallic materials. The thermal
conductivity decreases with temperature, and even at very high temperatures,
graphite becomes adiabatic. Graphite conducts electricity because each carbon
atom in graphite forms only three Covalent bonds with other carbons, each of
which remains one free electron to carry the charge.

3. Lubricity: the lubrication performance of graphite depends on the size of
graphite scales, the larger the scale, the smaller the friction coefficient, the
better the lubrication performance.

4.Chemical stability: Graphite in the room temperature has excellent chemical
durability, acid resistance, alkali resistance, and resistance to organic
solvent corrosion.

5.Plasticity: Graphite toughness is good, can be ground into a fragile
sheet.

6. Thermal shock resistance: Graphite in the room temperature when used to
withstand the dramatic changes in temperature without destruction, temperature
mutation, the volume of graphite changes little, will not produce cracks.

Application field

(1)Lithium battery industry

Natural graphite and artificial graphite are the primary sources of graphite
anode materials. Artificial graphite generally needs to go through calcination,
carbonization, high-temperature graphitization, coating, and other technological
processes; Natural graphite is mostly purified by alkali acid dressing,
ultra-high temperature purification, surface, and other processes.No matter
natural graphite or artificial graphite must undergo graphitization or wash at
high temperature, to become a cathode material for lithium battery production.
At present, high-temperature graphite purification technology, high-temperature
graphitization technology, has become the key technology in the research field
of graphite anode materials.

(2)Graphene industry

Compared with various preparation methods of graphene, graphite oxide
reduction method will become the most promising and promising method to
synthesize graphene and its materials. The primary raw material of graphite
oxide reduction method is high purity natural flake graphite.

(3)Isotropic nuclear graphite industry

Because high purity isotropic natural microcrystalline ink is an ideal raw
material for atomic graphite, it is particularly important to expand the source
of raw materials for high purity isotropic natural microcrystalline ink.

(4) Artificial diamond industry

Natural flake graphite powder is the primary raw material of synthetic
diamond. Scientists have proved that the purity of graphite powder and the
graphitization degree of graphite powder have a significant influence on product
quality. The selection of high purity graphite raw materials and the selection
of appropriate graphitization degree will be an essential way to improve the
product quality of an artificial diamond.

(5) Military graphite bomb industry

High purity graphite is the raw material for producing graphite bombs.

(6) Flexible graphite industry

To sum up, flexible graphite has a unique use value and broad development
prospect. But in the production process, there are purity requirements, chemical
acid purification often destroys or affect the excellent material properties,
high-temperature physical refinement has apparent advantages.

(7) Other trades

Natural high purity graphite powder has the advantages of high-temperature
resistance, good electrical and thermal conductivity, lubricity, chemical
stability, excellent wear resistance, can be used as synthetic crystalline
silicon carbide and boron carbide raw materials, hidden aircraft coating and
chemical industry, electronics, machinery, and other industrial fields, has an
extensive range of applications.

To sum up, the high purity graphite powder market has a broad prospect. It is
urgent to provide a large number of high-quality, high purity graphite powder
for the market.
