10kg 20kg 30Kg High Purity High Density Large Graphite Carbon Crucible

Description:

1. Strong chemical stability
Graphite has good chemical stability and is resistant to acid and alkali corrosion. After 1000 hours of salt spray testing according to GB/T 2423.17, the corrosion area is less than 5%, and it can be used in various chemical environments.

2. Low density advantage
The density of graphite is 1.6-2.1g/cm ³, which is about 1/4 of stainless steel and 1/2 of alumina. It is lightweight and has advantages in applications that require weight.

3. Low coefficient of expansion
At room temperature, the expansion coefficient of graphite is 2.0-4.0 * 10-6/℃, which is about 1/4 of stainless steel and 1/2 of alumina. It has good dimensional stability and is not easily deformed by temperature changes.

4. Excellent thermal shock stability
Graphite has excellent thermal shock stability, which can maintain stable performance even under temperature changes of △ T>1000 ℃ and withstand large temperature shocks.

5. High temperature resistance characteristics
The melting point of graphite is as high as 3850 ℃. In high temperature environments, its strength not only does not decrease, but also increases. For example, its tensile strength doubles at 2500 ℃, which can withstand extreme high temperature environments.

6. Excellent thermal conductivity
The in-plane thermal conductivity of graphite is as high as 100-400 W/(m · K), which can be close to the thermal conductivity of copper. The conventional thermal conductivity is 5-10 times that of alumina, and it can quickly conduct heat.

7. Good lubricity
Due to the interlayer sliding characteristics, the friction coefficient of graphite is as low as 0.1-0.3, which makes it easy to process and has low cutting resistance. It is often used as a lubricant.

  Applications:

1, Corrosion resistant material
Graphite, due to its excellent chemical stability, is widely used in the production of chemical equipment components such as pumps, valves, pipelines, and reactor liners to prevent chemical corrosion. At the same time, specially processed graphite has the characteristics of corrosion resistance, good thermal conductivity, and low permeability. It is widely used in the production of heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters, and other equipment. It is widely used in industrial sectors such as petrochemicals, wet metallurgy, acid and alkali production, synthetic fibers, and papermaking.

2, Sealing material
Graphite materials are used as sealing materials in the chemical industry due to their high density, high strength, excellent self-lubricating properties, and high wear resistance. The self-lubricating and high-temperature resistance of graphite make it an ideal material for sealing gaskets and rings, used to prevent chemical leakage. The lubrication performance of graphite varies with the size of the scales. The larger the scales, the lower the friction coefficient, and the better the lubrication performance. Graphite wear-resistant materials can be used under high temperature and high sliding speed conditions without the need for lubricating oil.

3, Electrode material
The conductivity of graphite makes it an ideal material for electrodes in electrolytic cells, widely used in processes such as chlor alkali industry and hydrogen production through water electrolysis. Graphite electrodes have excellent properties such as high temperature resistance, oxidation resistance, and good conductivity, which can meet the requirements of harsh conditions such as high temperature, high current density, and strong corrosive media.

4, High temperature furnaces and processing equipment
Graphite is also used in the manufacture of high-temperature furnaces and processing equipment, such as vacuum furnaces, which are crucial in processes such as heat treatment, vacuum casting, and electron beam welding. Graphite crucible is a commonly used container in high-temperature furnaces, which can withstand high temperatures and corrosive substances, ensuring the smooth progress of reactions. At the same time, graphite can also be used as graphite insulation boards and bases for vacuum smelting, as well as components such as high-temperature resistance furnace tubes.
