Other refractory materials for High temperature industry

Sic Carbide Graphite Crucible

Q:Can graphite crucibles be used for melting reactive metals?: No, graphite crucibles should not be used for melting reactive metals as they can react with certain elements at high temperatures, causing contamination and compromising the quality of the final product.

Q:Is it possible to repair a cracked or damaged graphite crucible?: No, it is not possible to repair a cracked or damaged graphite crucible. Graphite is a brittle material and once it is cracked or damaged, it cannot be repaired. It is recommended to replace the crucible to ensure proper functionality and safety.

Q:Why does the graphite crucible used for molten gold add a quartz coat?: The melting point of gold is 1063 degrees Celsius. At this temperature, graphite reacts with oxygen in the air to produce carbon dioxide. The quartz coat may be used to prevent leakage of graphite crucibles

Q:Can graphite crucibles be used for heat treatment processes?: Yes, graphite crucibles can be used for heat treatment processes. Graphite is known for its high melting point and excellent thermal conductivity, which makes it an ideal material for applications requiring high temperatures and efficient heat transfer. Heat treatment processes involve heating materials to specific temperatures to alter their physical or chemical properties. Graphite crucibles can withstand these high temperatures without melting or deforming, ensuring the stability and integrity of the heat treatment process. Additionally, graphite's low reactivity with most substances makes it suitable for a wide range of heat treatment applications, including annealing, tempering, quenching, and carburizing. Overall, graphite crucibles are a popular choice for heat treatment processes due to their high temperature resistance, thermal conductivity, and chemical inertness.

Q:How long does the graphite crucible extend its service life?: Must grasp the correct way to use, do not cause unnecessary losses, such as not take good, did not put, broken, and this is a great pity.

Q:What are the considerations for selecting a crucible tongs for handling graphite crucibles?: When selecting crucible tongs for handling graphite crucibles, there are a few important considerations to keep in mind. Firstly, it is crucial to choose tongs that are specifically designed for graphite crucibles. Graphite is a brittle material and can be easily damaged or broken if not handled properly. Therefore, the tongs should have a design that provides a secure grip without exerting excessive pressure on the crucible. Secondly, the length and size of the tongs should be appropriate for the size and weight of the graphite crucible. This ensures that the tongs provide sufficient leverage and control while handling the crucible, minimizing the risk of accidents or mishandling. Additionally, the material of the tongs should be carefully considered. It is advisable to opt for tongs made of heat-resistant materials like stainless steel or nickel alloy, as they can withstand high temperatures without warping or corroding. This is particularly important when working with graphite crucibles, as they are often used in high-temperature applications such as metal casting or melting. Lastly, ergonomics and comfort should not be overlooked. The tongs should have a comfortable grip that allows for easy and precise handling, reducing the strain on the operator's hand and wrist. This is especially important during prolonged or repetitive usage. Overall, selecting the right crucible tongs for handling graphite crucibles involves considering the design, size, material, and ergonomics to ensure safe and efficient handling of the crucibles.

Q:Is it possible to achieve a controlled atmosphere inside a graphite crucible?: Achieving a controlled atmosphere inside a graphite crucible is indeed possible. Graphite crucibles find common usage in high-temperature applications, particularly for melting metals and alloys. Various methods can be employed to achieve a controlled atmosphere. One approach involves the use of a gas purging system. This entails introducing a specific gas into the crucible to create the desired atmosphere. For instance, if an inert atmosphere is necessary, gases like argon or nitrogen can be used to displace any oxygen or other reactive gases present. The gas flow rate and pressure can be adjusted to maintain the desired atmosphere. Another method involves creating a sealed environment around the crucible. This can be accomplished by utilizing a furnace or an induction heating system equipped with a gas-tight enclosure. By controlling the gas composition and pressure within this enclosure, a specific atmosphere can be maintained surrounding the crucible. Moreover, the choice of crucible material is crucial to consider. Graphite possesses high thermal conductivity, allowing for rapid heat transfer. However, it can also react with certain gases or metals at elevated temperatures. Hence, selecting the appropriate grade of graphite and ensuring proper crucible conditioning are essential in maintaining a controlled atmosphere. Ultimately, by utilizing suitable equipment and employing effective techniques, it is feasible to establish a controlled atmosphere inside a graphite crucible, thereby enabling precise control of the environment during high-temperature processes.

Q:How does the porosity of graphite affect the performance of a crucible?: The porosity of graphite affects the performance of a crucible in several ways. Firstly, the porosity of graphite determines the crucible's ability to withstand high temperatures. A more porous graphite crucible will have a higher resistance to thermal shock, meaning it can withstand rapid changes in temperature without cracking or breaking. This is important in applications where the crucible is exposed to extreme heat, as it ensures the crucible remains intact and does not compromise the integrity of the material being heated. Secondly, the porosity of graphite also affects the crucible's ability to retain heat. A more porous crucible will have a larger surface area, allowing it to absorb and retain heat for longer periods. This is beneficial in applications where consistent and prolonged heating is required, as the crucible can provide a more stable temperature environment for the material being processed. Furthermore, the porosity of graphite can also influence the crucible's resistance to chemical corrosion. A more porous crucible allows for better diffusion of chemicals, reducing the risk of chemical reactions occurring on the surface of the crucible that could degrade its performance. This is particularly important in industries such as metallurgy or chemistry, where corrosive substances are commonly used. Overall, the porosity of graphite plays a significant role in determining the performance of a crucible. It affects its thermal shock resistance, heat retention capabilities, and resistance to chemical corrosion. Therefore, selecting a crucible with the appropriate porosity is crucial in ensuring optimal performance and longevity in various high-temperature applications.

Q:The difference between single graphite furnace graphite furnace atomic absorption spectrophotometer and double graphite furnace: 10-9g/ml orders of magnitude can be measured by Flame Atomic Absorption Spectrometry10-13g/ml order of magnitude can be measured by Graphite Furnace Atomic Absorption SpectrometryIn addition to its excellent performance, flame atomic absorption has been added with an on-line dilution device and switchable single - and double - path optical systems.Graphite furnace atomic absorption adopts transverse heating graphite tube, the heating speed can be as high as 3800K/ seconds, and can set up as many as 30 heating steps to suit all kinds of applications.

Q:What crucible can be used to make steel? At least 1500 degrees resistant: A graphite crucible is a very important purpose is to iron and steel. The oxidant using this process is oxygen. The air is blown into the molten iron, the impurity of silicon and manganese oxide. The release of large amounts of heat in the oxidation process (including 1% silicon iron can make the temperature rise of 200 Celsius), can make the furnace reach a high enough temperature. So the converter does not need the additional use of fuel.
