- Q:Can graphite crucibles be used for metal casting?
- Yes, graphite crucibles can be used for metal casting. Graphite is a common material used for crucibles in metal casting due to its high melting point and excellent thermal conductivity. It is particularly suitable for casting non-ferrous metals such as gold, silver, copper, and aluminum. Graphite crucibles can withstand high temperatures without cracking or deforming, making them ideal for melting and pouring molten metal. Additionally, graphite has low chemical reactivity, which prevents it from reacting with the metal being cast. This property ensures that the purity and quality of the final cast metal are maintained. However, it is important to note that graphite crucibles may not be suitable for casting certain metals with high melting points, such as steel, as they may not withstand the extreme temperatures required for melting these metals. In such cases, other materials like clay or ceramic crucibles may be more appropriate.
- Q:I'd like to smelt 104 aluminium alloy by medium frequency furnace. What should I pay attention to? Please point it out, thank you!
- Don't know what is your crucible material medium frequency furnace, if using graphite crucible, graphite as easily broken and easy to absorb moisture, must be handled with care to avoid the collision, but must be in use before the slow heating and drying, until the crucible to dark red, check no cracks can be put into the molten alloy. If the iron crucible, the Aluminum Alloy are strictly limited, so the iron, iron crucible, Tieshao, ladle, the tool must be coated with paint, paint is selling goods, components do not know, iron crucible and apparatus must also be preheated, exclusion of moisture. In addition, do not know you are refining aluminum ingot or making ah Aluminum Alloy parts, if the production parts should pay attention to defects of oxidation, slag and coarse grain, I am afraid that refining, refining agent are also ready to sell goods, how can read the instructions. Especially when smelting Caution!, preventing aluminum liquid splash, including many contents, such as inspection and testing, there is not much to say, the main note in the smelting process I thought so much, typing is slow, very hard ah, hey. Hope to be of some help to you.
- Q:Why is graphite crucible smelting reducing properties of the burden is particularly vulnerable to corrosion?
- Temperature, high temperature resistance of graphite crucible in general, is not easy to happen, but it is possible to make mistakes. May the general errors include: (a) graphite crucible is exposed in the atmosphere at high temperature (b) cooling too fast or quench.
- Q:You solved it. What happens if a quartz crucible is coated with a graphite crucible?
- The graphite crucible will burn on an alcohol burner, and the quartz crucible may cause cracks due to uneven heat.
- Q:What are the common uses of graphite?
- As a wear-resistant and lubricating material, graphite is often used as a lubricant in the mechanical industry. Lubricants can not be used in high speed, high temperature, high pressure conditions, and graphite wear-resistant materials can be at -200 - 2000 temperature, and at a high sliding speed, without lubricating oil work. Many transporting corrosive media devices are widely used, which is made of graphite material piston ring, the sealing ring and the bearing, they are running, without adding lubricating oil, graphite and many metal processing (drawing, drawing) the good lubricant.
- Q:Are graphite crucibles suitable for melting composite propellants?
- Graphite crucibles are generally not suitable for melting composite propellants. Composite propellants consist of a mixture of oxidizers, fuels, and binders, which can be highly reactive and corrosive. Graphite, although known for its high melting point and resistance to high temperatures, can react with certain components of composite propellants. Graphite crucibles can undergo chemical reactions and erosion when exposed to certain oxidizers, such as ammonium perchlorate, which is commonly used in composite propellants. This can lead to contamination of the propellant and affect its performance. Additionally, the binders used in composite propellants can also react with graphite, leading to degradation and potential failure of the crucible. For melting composite propellants, it is recommended to use crucibles made of materials specifically designed for this purpose, such as ceramic or refractory metal crucibles. These materials have better resistance to the corrosive nature of composite propellants and can withstand the high temperatures involved in the melting process.
- Q:Why do laboratory crucibles use ceramics instead of glass?
- The ceramic crucible does not soften and can withstand alkaline material.
- Q:What is the importance of carbon graphite as biological material?
- As a conductive material of graphite in the electrical industry widely used as electrode, brush, carbon, carbon nanotubes, mercury rectifier cathode, graphite gasket, telephone parts, TV tube coating etc.. The most widely application of graphite electrode in smelting, alloy steel, iron alloy, graphite electrode, the strong current through the melting zone, the arc electrode into the electric furnace, the electrical energy into heat, the temperature rises to 2000 degrees, so as to achieve the purpose of melting or reaction. In addition, in the electrolysis of metal, magnesium, aluminum and sodium, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace for carborundum is also made of graphite electrode as furnace head conducting material.
- Q:Melting the iron in the graphite crucible. Does the graphite in the crucible turn into carbon and it melts into the steel?
- Graphite burns at least 3000 degrees above the oxygen level. The ignition point in the air is even higher. There is no fire at such high temperatures in the air, so the graphite cannot be ignited.
- Q:Are graphite crucibles suitable for use in a vacuum environment?
- Yes, graphite crucibles are suitable for use in a vacuum environment. Graphite is a highly stable material that can withstand high temperatures and corrosive environments, making it a popular choice for various industrial applications including vacuum environments. Graphite crucibles have excellent thermal conductivity and resistance to thermal shock, which are important properties for maintaining temperature stability in a vacuum. Additionally, graphite has low outgassing properties, meaning it releases minimal gas or vapor when exposed to a vacuum, further making it suitable for use in such environments. Overall, graphite crucibles are a reliable and effective choice for conducting experiments or processes in a vacuum environment.
