- Q: Can a graphite crucible be used for melting einsteinium?
- No, a graphite crucible cannot be used for melting einsteinium. Einsteinium is a highly radioactive element with a melting point of 860 degrees Celsius. Graphite crucibles typically have a maximum working temperature of around 3000 degrees Celsius, which is sufficient for most metal melting applications. However, einsteinium's extreme radioactivity poses significant health risks, and it requires specialized handling and containment procedures. Additionally, the properties of einsteinium make it highly reactive and corrosive, which can cause damage to the graphite crucible. Therefore, a graphite crucible is not suitable for melting einsteinium, and alternative materials and containment methods must be used.
- Q: How do you use crucibles to process copper?
- The medium frequency furnace crucible is made of quartz sand lining material, and the crucible has a long service life, usually in three months. The power frequency furnace is also sintered with quartz sand.
- Q: Does a graphite crucible require any special handling during transportation?
- Yes, a graphite crucible requires special handling during transportation. Graphite is a brittle material that can easily crack or break if subjected to excessive pressure or impact. To ensure the safe transportation of a graphite crucible, it should be packaged securely in a padded or cushioned container to protect it from any potential damage. Additionally, it is important to handle the crucible with care, avoiding any rough or sudden movements that could cause it to hit against other objects or surfaces. By taking these precautions, the risk of damage to the graphite crucible during transportation can be minimized.
- Q: Corundum crucible and graphite crucibleSome enterprises use graphite crucibles in vacuum furnaces, while some larger ones use corundum crucibles. What I want to know is the advantages and disadvantages of corundum crucibles and graphite crucibles
- Corundum temperature limited, easily cracked at high temperature. But the chemical stability is good, do not use under vacuum. In contrast, corundum is much cheaper.
- Q: To sum up the different uses (and causes) of various crucibles in ChemistryQuartz glass crucibles, for examplealumina crucibleGlass crucibles, iron crucibles, and the like are different and should be noted
- Molten material with acid as flux (such as K2S, 207, etc.)Porcelain crucible: 1., heat resistance of about 1200 degrees2. suitable for K2S207 and other acidic substances melting samples3. generally can not be used for Na0H, Na202, Na2CO3 and other alkaline substances for melting flux, so as not to corrode the porcelain crucible. Porcelain crucible can not be contacted with hydrofluoric acid4. porcelain crucible can be diluted HCl boiling cleaningIron Crucible: iron does not react with sodium hydroxide, iron crucible can melt caustic soda, and iron crucible is used at 400 degrees or more. It is not economical, even if it is not melted, it also oxidizes rapidlyGraphite crucible: universal type graphite crucible and graphite crucible shaped and high pure graphite crucible three. Graphite crucible of various types, due to performance, and the use of different conditions, the raw material used, production method, technology and product specifications are different. Shi Mogan Guo is the main raw material, is the crystallization of natural shape it is graphite. It maintains the physicochemical properties of all kinds of natural right. That is: the original ink has good thermal conductivity and high temperature resistance, high temperature in use process, small thermal expansion coefficient, thermal quenching of, has a certain anti strain properties. The acid alkali solution, the corrosion resistance is strong, excellent chemical stability. The graphite crucible, because has more excellent performance, so in casting, metallurgy, machinery, chemical and other industrial sectors, is widely used for smelting alloy tool steel and non-ferrous metal and alloy smelting and has good. Technical and economic results
- Q: How long is the service life of the cast iron crucible?
- The service life of cast iron crucibles for electric furnaces ranged from 1 months to 2 months.
- Q: Why do laboratory crucibles use ceramics instead of glass?
- The ceramic crucible does not soften and can withstand alkaline material.
- Q: Can graphite products be calcined in air for a long time?
- Because graphite has many excellent properties, it has been widely used in metallurgy, mechanical, electrical, chemical, textile, national defense and other industrial sectors. Refractory material. The graphite product keeps the original chemical properties of flake graphite and has a strong self lubrication performance. The characteristics of graphite powder is of high strength, corrosion resistance and acid resistance of the high temperature of 3000 DEG C and resistance to low temperature of -204 DEG C, and its compressive strength is greater than 800kg/Cm2, and the antioxidant, at 450 degrees Celsius in the air was 1%, rebound rate of 15-50% (density 1.1-1.5). Therefore, graphite products have been widely used in metallurgy, chemical, petrochemical, high energy physics, aerospace, electronics and so on.
- 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 porcelain crucible with a small hole under it?
- The crucible can be divided into three categories: graphite crucible, clay crucible and metal crucible. In the graphite crucible, there are three kinds of universal graphite crucible and special graphite crucible and high-purity graphite crucible. Various types of graphite crucibles, because of their performance, application and application conditions, are different in raw materials, production methods, process technology and product models and specifications.
