Advantages of graphite box

Graphite boxes are usually square, round and other regular shapes, easy to install and use.

Excellent thermal stability

It can maintain structural stability in extreme temperature environments from -200°C to 1000℃ and even higher. And it will not easily deform or damage.

Extremely stable chemical properties

It has good corrosion resistance, and almost does not react with common chemical substances such as acid and base.

Gute elektrische Leitfähigkeit

It can conduct current efficiently in some scenes involving electrochemical reactions.

Hohe mechanische Festigkeit

It can resistant to pressure and wear, and has long service life.

Moreover, the thermal conductivity of it is high, which can transfer heat quickly and evenly. And ensure the balanced distribution of temperature in the hot processing process.

Uses of graphite box

• Lithium battery material preparation field：

Lithium iron phosphate battery sintering

Graphite box has excellent high temperature resistance, stable resistance to over 1000℃ high temperature, and stable structure. Its relatively closed space can avoid the mixing of impurities, ensure the purity of the material. And it allows the heat to transfer evenly, so that the sintering is sufficient. This is conducive to the formation of ideal crystal structure and improve the performance of the battery.

High temperature carbonization of negative electrode material

This process is carried out at 800-1500 ℃, and the graphite box can prevent the oxidation of the material. It ensures the uniform distribution of heat, helps to fully carbonize, forms a carbon structure with good performance. And lay the foundation for the preparation of the negative electrode of the high-performance lithium battery.

Metallurgy:

In the process of metal smelting, you can often use graphite box as Schmelztiegel. Its chemical properties are stable and can prevent chemical reactions between metals and other substances. To ensure the smooth progress of the metal melting process and ensure the purity and quality of the metal. At the same time, in the purification process of some special metals, it can also play an important role in helping to remove impurities, and improve the purity of the metal.

Electronics industry:

In the semiconductor manufacturing process, you can use graphite box in the heat treatment process of chips. It can provide a stable high temperature environment for the chip, and will not introduce impurities. To ensure the performance and reliability of the chip. In addition, in the sintering process of electronic components, you can also use it as a carrying device. Using its good heat conduction performance, so that the electronic components are heated evenly and improve the sintering quality.

Chemical industry:

In chemical synthesis reactions, if the reaction needs to be carried out in a high temperature, high pressure and corrosive environment, you can use it as reaction containers. Its chemical stability and high temperature and high pressure resistance can effectively resist the corrosion of chemical substances. To ensure the safety and stability of the reaction. At the same time, in the drying and roasting process of some chemical products, it can also play a role to help achieve efficient drying and roasting operations.

Other uses of graphite boxes

High temperature heat treatment furnace

Graphite box can provide a relatively independent high temperature environment for the items to be treated. And its excellent thermal conductivity helps to evenly heat and improve the treatment effect.

Powder metallurgy casting

You can commonly use it to contain powder raw materials. During the casting process, graphite box can withstand high temperature and prevent powder oxidation, which is conducive to obtaining high-quality metallurgical castings.
