Advanced Porous Graphite

Advanced Porous Graphite, as the name suggests, is a type of graphite that contains interlinked voids or pores in its structure. The size of these pores can vary greatly, which affects the performance characteristics of the material.

Characteristics of Advanced Porous Graphite

●  Large Surface Area and Strong Adsorption Capacity: 

One of the most outstanding advantages of porous graphite is its much larger surface area compared to non-porous graphite, which makes it very adsorbent.

●  Excellent thermal and electrical conductivity: 

Porous graphite has excellent thermal and electrical conductivity. This property is particularly important in applications that require heat dissipation or electrical conductivity.

●  Excellent mechanical strength: 

The mechanical strength of porous graphite is related to its pore structure and manufacturing process. The mechanical strength of porous graphite is not as good as non-porous graphite, but its mechanical properties are still excellent.

●  Chemical inertness: 

As a graphite product, porous graphite is chemically inert and can work in corrosive environments. Chemical inertness helps porous graphite be used in chemical processes that require resistance to acids, bases, and solvents.

●  Manufacturability and high customizability: 

The pore structure of porous graphite can be customized in many ways. Techniques such as chemical vapor deposition can be used to achieve the pore size and distribution desired by the customer.

Applications of Advanced Porous Graphite

●  SiC crystal growth：

Studies have shown that in the crystal growth of SiC, the application of porous graphite helps to reduce the number of microtubules and other defects, and reduce the content of impurity elements in the crystal, so porous graphite can bring great help in the production of SIC crystals.

●  Wafer fabrication: 

Due to its excellent thermal conductivity and corrosion resistance, porous graphite can be used to manufacture wafer carriers such as graphite boats and graphite chucks. The porous graphite is able to work stably in high temperature environments, helping the wafer to maintain a uniform temperature distribution, thus ensuring processing accuracy.

●  Chemical vapor deposition (CVD) : 

Porous graphite is resistant to high temperature and chemically inert, so it is often used as a reactor liner and electrode material as part of the CVD process to promote high-quality film deposition.

●  Heat dissipation of semiconductor devices: 

The excellent thermal conductivity of porous graphite makes it an ideal choice for heat dissipation solutions in semiconductor devices. It can be made into heat sink or thermal interface material to help fast heat dissipation and improve the working efficiency and life of the device.

●  Etching and etching processes: 

In the dry etching process of semiconductor manufacturing, porous graphite can be used as an electrode material or a cathode material, and its corrosion resistance and electrical conductivity help it withstand the erosion of corrosive plasma, ensuring the stability and precision of the etching process.

●  High purity applications: 

Porous graphite is refined to meet the semiconductor industry's strict requirements for material purity and reduce the impact of impurities
