Graphite&Carbon
Graphite products
ZhaoChen's special carbon products are manufactured and processed using the properties of carbon and graphite and are widely used in the fields of semiconductors, automobiles and steel.
What are Specialty Carbon Products?
It does not refer to a specific product, but rather utilizes the properties of graphite or carbon.
Carbon/graphite products made by cutting carbon/graphite materials.

graphite
Graphite = Graphite
There is natural graphite (graphite) obtained from natural minerals, and artificial graphite made from petroleum and coal. Graphite is a sintered body of carbon particles with a graphite crystal structure.
<Features>
- Thermal conductivity, heat resistance, thermal shock resistance
- Conductivity
- Lightweight and easy to process
- Chemical resistance
- Self-lubricating
<Graphite Material Manufacturing Process>
① Use petroleum coke and asphalt coke as raw materials, use a crusher to make them into particles, and use a sieve to grade them ② Add coal tar asphalt and knead them into a paste ③ Molding → Calcination → Graphitization
[Types of graphite]
CIP molding materials
CIP (Cold Isostatic Press) is a cold isostatic press, also known as isotropic graphite.
<Features>
▶︎During molding, the raw materials are placed in the rubber container mold and the 6 sides are pressed equally, so that the force is even and the strength of each side of the material varies little.
Superior to other molding methods
Extrusion materials
Anisotropic graphite is made by placing the raw material into an extrusion die, applying pressure from one end, and extruding it through a nozzle.
<Features>
▶︎Slightly rough texture ▶︎Lower material cost than CIP ▶︎Excellent results can be obtained for large items such as furnace plates and trays and simple applications
<Application>
Refined electrode materials:
Tray material for high temperature furnace, ETC.
[特種石墨]
Low dust graphite
LGPC (Low Graphite Particle Carbon)
<Features>
▶︎The raw materials are screened into ultra-fine powders, mixed with glass carbonized materials, and filled with inter-particle gaps to prevent graphite powder from falling off when using graphite materials. It is not easy to react with metal materials, etc. There is less adsorption and emission of impurity gases. High purity, very little metal impurity content. It can meet various shape requirements without affecting the dimensional accuracy of the product. To achieve higher density, the particles have higher adhesion, and the amount of powder falling is reduced to 75% of the original graphite powder falling.
高硬度石墨
HGPC（High Graphite Particle Carbon）高硬度石墨顆粒碳素
<特點>
▶︎是一種堅硬、耐磨的材料，可在當前和下一代離子植入設備(Ion Implanter)中提供更高的性能。獨特的製造工藝可生產出具有更高硬度和強度的石墨，即使在最高能耗的環境中也能減少磨耗和粉塵顆粒。
