Company Information

Sic Graphite Crucible 2015

Q:How long is the service life of the cast iron crucible?: Now basically no trial of cast iron crucible, graphite crucible is a cast iron crucible, the general can only use a month or so, now the shortest graphite crucible can be used for half a year, Wuxi branch cast Trade Co., a cast card graphite crucible

Q:Can a graphite crucible be used for high-temperature reactions?: Yes, a graphite crucible can be used for high-temperature reactions. Graphite has a high melting point of around 3,500 degrees Celsius, making it suitable for withstanding extreme temperatures. It also has excellent thermal conductivity, which allows for efficient heat transfer and uniform heating of the reactants. Additionally, graphite is chemically inert and has low reactivity, making it resistant to corrosion and suitable for various chemical reactions. Therefore, a graphite crucible is commonly used in high-temperature applications such as melting metals, pyrolysis, and other thermally-driven reactions.

Q:Can graphite crucibles be used for carbonization processes?: Yes, graphite crucibles can be used for carbonization processes. Graphite is an excellent material for high-temperature applications due to its superior thermal conductivity and resistance to thermal shock. In carbonization processes, where carbon-rich materials are heated to high temperatures in the absence of oxygen, graphite crucibles are commonly used to contain and heat the materials. The high thermal conductivity of graphite ensures efficient heat transfer, enabling uniform heating and minimizing heat loss. Additionally, graphite's resistance to thermal shock allows it to withstand rapid temperature changes during the carbonization process. Overall, graphite crucibles are a reliable and suitable choice for carbonization processes.

Q:Can a graphite crucible be used for laboratory applications?: Yes, a graphite crucible can be used for laboratory applications. Graphite has excellent thermal conductivity and resistance to high temperatures, making it suitable for various laboratory processes such as melting, heating, and chemical reactions. It is commonly used in applications like sample preparation, metal analysis, and organic synthesis in laboratories.

Q:Can graphite crucibles be used for melting rare earth metals?: Melting rare earth metals is possible using graphite crucibles. Graphite possesses desirable qualities like a high melting point, excellent thermal conductivity, and resistance to chemical reactions. These properties make graphite an ideal material for applications that involve high temperatures, such as melting rare earth metals. Moreover, graphite crucibles are durable and can endure the harsh conditions associated with molten metals. This makes them a suitable choice for the melting and refining of rare earth metals. Nevertheless, it is crucial to acknowledge that certain rare earth metals, like cerium, can react with graphite when exposed to high temperatures. This can lead to the formation of carbonates. Hence, it is advisable to carefully consider the specific properties and reactivity of each rare earth metal before employing graphite crucibles for the purpose of melting.

Q:What is the conductivity of graphite and copper, iron and zinc?: Graphite and copper, iron, and zinc are electrically conductive. The conductivity and thermal conductivity are different for different grades of materials. It is necessary to determine the material or grade of the graphite to have the corresponding technical parameters. The letter Ruida graphite thermal field | graphite heater | graphite crucible | isostatic graphite, when processing will also consider these problems, depends on the specific application!

Q:Are there different sizes available for graphite crucibles?: Indeed, graphite crucibles are offered in various sizes to cater to diverse needs and applications. These crucibles come in a plethora of sizes, ranging from petite ones suitable for jewelry making or minor laboratory experiments to more substantial ones used for industrial purposes such as metal casting or melting. The necessary size of the crucible is contingent upon the quantity of material to be melted or processed, as well as the unique demands of the application at hand. Consequently, an array of sizes is made available to satisfy distinct requirements and guarantee the optimal and proficient utilization of graphite crucibles.

Q:How is a graphite crucible used in the production of carbon composites?: A graphite crucible is essential in the production of carbon composites as it serves as a container to hold and melt the raw materials that are used to create the composites. The crucible is made of graphite because it is able to withstand extremely high temperatures without melting or reacting with the molten materials. Once the materials are melted in the crucible, they can be poured or molded into the desired shape to form the carbon composite.

Q:Why are there too many impurities in the gravity casting products of aluminum alloy, so they can not be welded well by argon arc welding?: The official must before casting of aluminum liquid refining slag and gas, because the melting use graphite crucible furnace or silicon carbide crucible furnace refining, so do not suggest that the addition of a solvent in order to avoid corrosion of crucible, the best refining slag degassing process is the use of rotary degassing machine by introducing inert gas such as nitrogen and argon (the best), impurity and hydrogen in liquid aluminum removal, complete slag removal and gas to test the effect of slag by K model, and use the detection instrument for measuring hydrogen hydrogen content, to meet the requirements after the investment casting used.

Q:Can graphite crucibles be used for powder coating?: It is not possible to use graphite crucibles for powder coating. Powder coating is a process where a dry powder is applied onto a surface using electrostatic attraction. Graphite crucibles, on the other hand, are containers that can withstand high temperatures and are used for melting metals and other high-temperature applications. However, they are not suitable for powder coating. To achieve the desired results in powder coating, specific equipment like spray guns or electrostatic powder coating systems are required to evenly and effectively apply the powder onto the surface. Using graphite crucibles for powder coating would not yield the desired outcome and could potentially damage the crucible and compromise the powder coating process.
