Detailed Product Description

high purity graphite block, has good mechanical and chemical behaviours

High Purity Graphite is suitable for the graphite( anode, inner grid, outside grid,reverberation pole, and excitation) which is applied in all kinds of small size silver rectifier, and for the graphite(anode, grid) which is appplied in electronics tubes. It is used in monocrystal furnace as grapite heater, heating preservation cover,crucibles etc. The specification that our company mainly produces is as follows: Dia.40mm---275mm; height 100---150 and 2*120, 200*200, 200*320(Cube); Thickness 50---12. The special request can be customized.

Q: Can graphite crucibles be used for thermal analysis?: Thermal analysis does not usually involve the use of graphite crucibles. Graphite crucibles are primarily utilized for high temperature purposes, such as the melting and casting of metals, as well as chemical reactions that necessitate intense heat. When conducting thermal analysis, diverse techniques are employed to examine the physical and chemical properties of materials during temperature changes. Some of these techniques comprise differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and measurements of thermal conductivity, among others. To carry out these types of analyses, specific equipment and materials are required. Generally, ceramic or metal crucibles are utilized due to their superior thermal conductivity and stability at high temperatures, which ensures precise and dependable measurements. These crucibles are engineered to endure thermal cycling and provide a controlled environment for the analyzed sample.

Q: Can industrial induction furnaces heat graphite?: However, it can heat something else and then heat the graphite by heat transfer.

Q: Can graphite crucibles be used for semiconductor manufacturing?: Graphite crucibles, unfortunately, cannot fulfill the needs of semiconductor manufacturing. They find their utility in industries such as metallurgy and foundries, where they exhibit exceptional thermal conductivity and endure high temperatures. Nevertheless, in the realm of semiconductor manufacturing, demands take an entirely different shape. This field involves meticulously controlled and precise procedures, where contamination poses a significant threat. Graphite crucibles indiscriminately release carbon particles that taint the semiconductor materials, consequently compromising their performance. Thus, semiconductor manufacturing necessitates crucibles crafted from materials like quartz or ceramic. These alternatives boast minimal contamination levels and possess the resilience essential for enduring the rigorous temperatures and chemical environments characteristic of fabrication processes.

Q: How does the wall thickness of a graphite crucible affect the melting process?: The melting process is significantly influenced by the thickness of the graphite crucible walls. The walls' thickness determines both the crucible's heat transfer rate and overall efficiency. If the wall is thicker, it possesses greater thermal mass, enabling it to absorb and retain more heat. This proves advantageous in applications where a gradual and controlled heating or cooling process is desired. The increased thermal mass aids in stabilizing the temperature, preventing rapid fluctuations that can negatively impact the melting process. Alternatively, a thinner wall possesses less thermal mass and facilitates faster heat transfer. This proves beneficial when quick and efficient melting is required. The thinner walls allow for swifter heat transfer to the material being melted, resulting in shorter melting times and increased productivity. However, it is crucial to note that a thinner wall may be more susceptible to thermal stress and cracking due to the greater temperature differentials between the inner and outer parts of the crucible. This can potentially contaminate the melted material or even cause the crucible to fail. Moreover, the wall thickness affects the crucible's overall durability and lifespan. Thicker walls generally exhibit greater resistance to wear and tear, providing a longer operational life. This becomes particularly important in high-temperature applications where the crucible is exposed to extreme conditions. To summarize, the wall thickness of a graphite crucible directly impacts the melting process. Thicker walls provide improved temperature stability but may result in longer melting times, while thinner walls allow for faster heat transfer but may be more susceptible to thermal stress. Selecting the appropriate wall thickness depends on the specific requirements of the melting process and should be carefully considered to achieve optimal results.

Q: Can a graphite crucible be used for melting pharmaceutical substances?: Certainly, melting pharmaceutical substances is possible using a graphite crucible. Graphite crucibles possess desirable characteristics such as a high melting point, exceptional thermal conductivity, and chemical inertness, which render them appropriate for various applications, including pharmaceutical substance melting. They can endure the elevated temperatures required for the melting procedure without undergoing any reactions with the substances themselves, thereby guaranteeing the purity and integrity of the pharmaceutical compounds. Furthermore, graphite crucibles efficiently facilitate heat transfer, enabling uniform heating and melting of the pharmaceutical substances. Nonetheless, it is crucial to ensure that the graphite crucible is thoroughly cleansed and devoid of any impurities that could potentially compromise the purity of the pharmaceutical substances being melted.

Q: What are the differences in production techniques for different graphite crucible models?: This paper introduces the production technology of graphite crucible, process forming method, technological process and requirements of production process and process of coating and sintering.

Q: Is it possible to achieve controlled pouring with a graphite crucible?: Yes, it is possible to achieve controlled pouring with a graphite crucible. Graphite crucibles are widely used in various industries, including metal casting and melting, due to their unique properties. Graphite has a high melting point, excellent thermal conductivity, and good resistance to thermal shock, making it suitable for handling high-temperature materials. To achieve controlled pouring with a graphite crucible, several factors need to be considered. Firstly, the crucible should be properly preheated to the desired pouring temperature. This ensures that the molten material remains at the desired temperature during pouring, preventing premature solidification. Secondly, the design of the crucible and its pouring lip should allow for precise control over the flow of the molten material. The pouring lip can be shaped to achieve a steady and controlled stream, reducing the risk of splashing or spilling. Furthermore, the operator's skill and experience play a crucial role in achieving controlled pouring. They need to have a good understanding of the material being poured, its characteristics, and the appropriate pouring techniques. They should also be aware of any potential hazards and take necessary precautions to ensure safety during the pouring process. In summary, while achieving controlled pouring with a graphite crucible is possible, it requires proper preheating, appropriate crucible design, and skilled operators. By considering these factors, it is possible to achieve precise and controlled pouring for various applications.

Q: Why do laboratory crucibles use ceramics instead of glass?: Because the ceramic crucible heats the alkaline solution, the glass crucible doesn't work. If you have any help, please accept it. Then click on the top right corner of the phone. Thank you!!

Q: Can graphite crucibles be used for plasma arc melting?: Yes, graphite crucibles can be used for plasma arc melting. Graphite crucibles are known for their high thermal conductivity and resistance to high temperatures, which makes them suitable for use in various high-temperature applications. Plasma arc melting, which involves the use of an electric arc to generate and sustain a plasma state, requires a crucible that can withstand the intense heat generated during the process. Graphite crucibles are able to withstand these high temperatures and provide a stable and durable container for the molten material produced during plasma arc melting. Additionally, graphite crucibles offer good chemical resistance and can handle corrosive materials that may be present during plasma arc melting. Overall, graphite crucibles are a commonly used and effective choice for plasma arc melting applications.
