Q: Can graphite crucibles be used for carbon nanotube synthesis?: Yes, graphite crucibles can be used for carbon nanotube synthesis. Graphite has high thermal conductivity and can withstand high temperatures, making it suitable for growing carbon nanotubes through chemical vapor deposition methods.

Q: What is the white product in the crucible?: Reacts with oxygen in the air to produce a white Zinc Oxide, producing white smoke, which does not melt into brass liquid, and the remaining copper in the crucible is also Zinc Oxide, so the phenomenon that you describe

Q: Can graphite crucibles be used for precious metal refining?: Yes, graphite crucibles can be used for precious metal refining. Graphite crucibles are commonly used in the metallurgical industry due to their high temperature resistance and chemical inertness. They can withstand the intense heat required for the refining process and prevent contamination of the precious metals.

Q: Can graphite crucibles be used for melting pharmaceutical compounds?: Yes, graphite crucibles can be used for melting pharmaceutical compounds. Graphite crucibles are known for their high melting point, which makes them suitable for high-temperature applications such as melting metals, alloys, and even certain chemicals. Since pharmaceutical compounds can have different melting points, it is important to ensure that the temperature range of the graphite crucible is compatible with the melting point of the specific compound being melted. Additionally, graphite crucibles are chemically inert and have low reactivity, which reduces the risk of contamination or chemical reactions with the pharmaceutical compounds during the melting process. However, it is essential to consider the specific requirements and properties of the pharmaceutical compound being melted to ensure compatibility with the graphite crucible.

Q: How do you determine the appropriate crucible pouring spout for a specific application?: To determine the appropriate crucible pouring spout for a specific application, several factors need to be considered. Firstly, the material being melted or poured plays a crucial role in selecting the spout. Different materials have varying temperature requirements, viscosity, and reactivity, which will influence the type of spout needed. Secondly, the size and shape of the crucible are important considerations. The spout should be compatible with the crucible's dimensions and design to ensure a proper fit and efficient pouring. Additionally, the desired pouring rate and accuracy are important factors. Some applications require a fast and controlled pouring, while others may require a more precise and controlled flow. The shape and size of the spout should align with these requirements. Lastly, safety considerations should not be overlooked. The spout should be designed to minimize the risk of splashing, spilling, or other accidents during pouring. Overall, by considering the material, crucible dimensions, pouring requirements, and safety, one can determine the appropriate crucible pouring spout for a specific application.

Q: How do you determine the appropriate crucible stirring rod for a specific application?: To determine the appropriate crucible stirring rod for a specific application, several factors need to be considered. First, you need to assess the type of material being stirred in the crucible. Different materials may require different types of stirring rods to ensure efficient mixing and prevent contamination. For example, if you are stirring a corrosive substance, you would need to choose a stirring rod made from a material that is resistant to corrosion, such as stainless steel or PTFE (polytetrafluoroethylene). Secondly, the size and shape of the crucible should be taken into account. The stirring rod should be long enough to reach the bottom of the crucible and should have a shape that allows for effective stirring without causing excessive splashing or turbulence. Furthermore, the temperature and pressure conditions of the application should be considered. High temperatures or pressures may require the use of stirring rods made from heat-resistant materials, such as quartz or ceramic. Lastly, the specific requirements of the experiment or process should also be considered. If precision and accuracy are crucial, you may need to choose a stirring rod with a specific shape or design that allows for precise control of the mixing process. In summary, selecting the appropriate crucible stirring rod for a specific application involves considering the type of material being stirred, the size and shape of the crucible, the temperature and pressure conditions, and the specific requirements of the experiment or process. By carefully evaluating these factors, you can choose a stirring rod that ensures effective mixing and optimal results.

Q: What are the differences between quartz crucibles and glass crucibles in appearance, properties, uses, etc.?: Personally, I think that the short duration of sodium hydroxide in the quartz bottles should be no problem. As long as the inner wall is smooth, it is important to note that the stopper must not be used to grind the plug

Q: How do you prevent overheating of a graphite crucible?: There are several measures that can be taken to prevent overheating of a graphite crucible: 1. Careful temperature control is essential. It is crucial to monitor and regulate the temperature of the furnace or kiln where the graphite crucible is being used. By keeping the temperature within the recommended range, overheating of the crucible can be avoided. 2. Insulating the furnace or kiln adequately can help maintain a stable temperature and prevent excessive heat transfer to the graphite crucible. By using high-quality insulation materials and ensuring proper installation, the risk of overheating can be effectively reduced. 3. It is important to avoid sudden temperature changes, as they can cause thermal shock and lead to cracks or failure of the crucible. Extreme temperature variations should be avoided, especially when the crucible is already hot. 4. Proper handling and storage of graphite crucibles are crucial. They should be handled with care to prevent any damage that could compromise their integrity. When not in use, they should be stored in a dry and cool environment, away from direct sunlight and sources of excessive heat. 5. Regular maintenance is essential. The graphite crucible should be inspected regularly for any signs of wear, cracks, or damage. If any issues are identified, the crucible should be replaced promptly to prevent the risk of overheating and potential accidents. By following these preventive measures, the lifespan of the graphite crucible can be enhanced, and the risk of overheating can be minimized, ensuring optimal performance in various high-temperature applications.

Q: Single crystal furnace quartz crucible cast 22 inch 175 kilograms of feed it: Back chaos, in fact we are very worried about the recovery of this material strength and composition by crucible crucible change can not be used, but also fast, so the results will soon be out.

Q: Can I add a graphite furnace to the East and West aa-7002?: Graphite furnace atomic device is a type of system will be placed in the pipe wall, graphite platform, carbon sample holes or graphite crucible with electric heating to a high temperature to achieve atomization.
