Other refractory materials for High temperature industry
- Q:How to maintain the graphite crucible?
- In this way, the graphite crucible can not be used when the graphite crucible is used, and the residue left in the graphite crucible is damaged by the graphite crucible itself
- Q:Can a graphite crucible be used for aluminum melting?
- Yes, a graphite crucible can be used for aluminum melting. Graphite is a commonly used material for crucibles due to its high melting point, thermal conductivity, and resistance to chemical attack. It can withstand the high temperatures required for melting aluminum, which typically range from 660°C to 700°C (1220°F to 1290°F). Additionally, graphite crucibles have good thermal shock resistance, allowing them to handle the rapid temperature changes associated with the aluminum melting process. However, it is important to note that graphite crucibles may oxidize at high temperatures, leading to the formation of a graphite oxide layer on the crucible's surface. This oxide layer can affect the purity of the melted aluminum. Therefore, it is advisable to use a new or properly cleaned graphite crucible to minimize any potential contamination.
- Q:Is graphite crucible resistant to hydrofluoric acid?
- Mainly depends on the use of working conditions, the use of air, then more than 600 degrees Celsius will begin to be oxidized, and the service life will not be long.
- Q:How long will it take to warm the water at 20 degrees to 3000 degrees at 3800?
- You don't want it either, because the thermodynamic chart is the highest, that is, the superheated vapor data of the 1000C. In addition, in the absence of a catalyst, at 1800K and 1mmHg, the water vapor begins to decompose into H2, O2, H, O, OH. At 3500K, all the water vapor breaks down into H, O atoms.
- 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:How do you prevent graphite crucibles from cracking during cooling?
- To prevent graphite crucibles from cracking during cooling, it is important to follow these measures: 1. Gradual cooling: Avoid exposing the crucibles to abrupt temperature changes. Allow them to cool down slowly and naturally, as rapid cooling can cause thermal shock and lead to cracking. 2. Use insulating materials: Place the crucibles on an insulating pad or use insulating materials like ceramic fiber blankets or boards. These materials help to regulate temperature and reduce heat transfer, minimizing the risk of cracking. 3. Avoid direct contact with water: Graphite crucibles should not be directly exposed to water or other coolants immediately after use. Allow them to cool down at room temperature first, and then carefully clean them without sudden temperature changes. 4. Handle with care: When moving or handling hot crucibles, ensure proper support and use heat-resistant gloves or tongs. Sudden impacts or mishandling can cause stress and lead to cracking. 5. Preheat and anneal: Before initial use, it is recommended to preheat new crucibles gradually to remove any residual moisture. Similarly, annealing crucibles periodically at lower temperatures can relieve internal stress, reducing the chances of cracking during cooling. By following these precautions, one can minimize the risk of graphite crucible cracking and extend their lifespan.
- Q:Is it possible to repair a cracked graphite crucible?
- Yes, it is possible to repair a cracked graphite crucible. One method is to use a high-temperature epoxy or adhesive specifically designed for graphite materials. The crucible should be thoroughly cleaned and dried before applying the adhesive. The cracked area can then be carefully aligned and the adhesive applied, following the manufacturer's instructions. After the adhesive has cured, the crucible should be tested for any leaks or weaknesses before using it again. However, it is important to note that the repaired crucible may not have the same strength and durability as a new one, so it should be used with caution and closely monitored during use to prevent any further damage. In some cases, it may be more practical and cost-effective to replace the crucible rather than attempting a repair.
- Q:Why is the crucible burned and then black, oxidized, chemically?
- If the crucible is heated by an alcohol lamp, the black substance, which is the main component of the black substance after the fire has been burned, is one of the carbon elements, chemically called C., which is produced by incomplete combustion of alcohol
- Q:What magnetic material is sintered with large corundum crucible?
- Corundum temperature limited, easily cracked at high temperature.
- Q:Can waste circuit boards be recycled?
- When the filtrate is concentrated to silver nitrate, the crystallization of silver nitrate is transferred and filtered, and all the silver nitrate crystals are precipitated and absorbed. Finally, the silver nitrate is put into the dryer and dried to be used. If the purity of the silver nitrate is not high, multiple crystallization can be used to increase purity.
