- Q: What are the carbon elements? What are their structures? What are their properties and uses?
- C60 molecule is a molecule made up of 60 carbon atoms. It is similar to football, so it is also called "football"C60 is a stable molecule formed solely by carbon atoms. It has 60 vertices and 32 faces, of which 12 are pentagonal and 20 are regular hexagons. The relative molecular weight is about 720.
- Q: Can graphite crucibles be used for alloy preparation?
- Alloy preparation can indeed utilize graphite crucibles. These crucibles find wide usage in metallurgy and foundry applications owing to their remarkable attributes such as high melting point, chemical resistance, and thermal conductivity. The ability to endure the high temperatures essential for alloy preparation and the capability to melt different metals and alloys make graphite crucibles highly suitable. Furthermore, the melting process benefits from the stability and control provided by graphite crucibles, enabling precise alloy composition and uniformity. Moreover, graphite crucibles exhibit exceptional resistance to thermal shock, ensuring they remain intact even during sudden temperature fluctuations. Consequently, graphite crucibles emerge as a dependable choice for alloy preparation across diverse industries like automotive, aerospace, and manufacturing.
- 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: When decomposing iron ore, why should it be carried out at low temperature?
- The commonly used acid decomposition method is as follows:(1) hydrochloric acid decomposition of iron ore can generally be heated by hydrochloric acid decomposition, iron silicate soluble in hydrochloric acid, can add a little hydrofluoric acid or ammonium fluoride, the sample is completely decomposed. The dissolution rate of magnetite is very slow, add a few drops of stannous chloride solution, the decomposition speed is.(2) sulfuric acid hydrofluoric acid decomposition sample, in the platinum crucible and the plastic crucible, adds 1:1 sulfuric acid 10 drops, hydrofluoric acid 4-5ml, the low temperature heats up, when will emit three oxidation two sulfur white smoke, extracts with hydrochloric acid.(3) when sulfuric acid or sulfur phosphorus mixed acid (1:2) dissolves, the ore needs to be heated until the water is completely evaporated, and the white smoke of three sulfur trioxide is added, and then heated for several minutes. But the heating time should not be too long to prevent the formation of pyrophosphate.
- Q: Does a graphite crucible react with any substances during use?
- No, a graphite crucible does not react with any substances during use.
- Q: Is pig iron smelted in a graphite crucible?
- The ironmaking raw materials with iron ore (Fe2O3), smelting iron ore, coke (fuel), limestone (solvent) and charge together into the blast furnace, under certain temperature and pressure, through a series of chemical reactions, the reduction of iron ore.
- Q: Can graphite crucibles be used for melting rare earth metals?
- Yes, graphite crucibles can be used for melting rare earth metals. Graphite is known for its high melting point, good thermal conductivity, and resistance to chemical reactions, making it an ideal material for high-temperature applications such as melting rare earth metals. Additionally, graphite crucibles are durable and can withstand the harsh conditions of molten metals, making them a suitable choice for melting and refining rare earth metals. However, it is important to note that some rare earth metals, such as cerium, can react with graphite at high temperatures, leading to the formation of carbonates. Therefore, it is advisable to consult the specific properties and reactivity of each rare earth metal before using graphite crucibles for melting.
- Q: How do you prevent contamination from the graphite crucible during melting?
- To prevent contamination from the graphite crucible during melting, several measures can be taken. One approach is to ensure that the crucible is thoroughly cleaned and free from any impurities before use. Additionally, using high-quality graphite crucibles that are specifically designed for high-temperature applications can minimize the risk of contamination. It is also crucial to handle the crucible with clean and dry tools to avoid introducing foreign substances. Finally, maintaining a controlled and stable melting environment, such as using a protective atmosphere or vacuum, can further prevent contamination by preventing the reaction of the crucible with surrounding gases or materials.
- Q: What are the technical specifications of graphite crucibles?
- Crucible; physical and chemical index; standard parameter; test dataThe refractoriness is 1680 degrees, and the refractoriness is 1685Carbon content 38%, carbon content 41.46%Porosity less than 35% porosity is less than 32%Volume density 1.6g/cm3 volume density 1.71g/cm3The above data are referred to Qingdao Huatai graphite, hope to adopt, thank you.
- Q: Can a graphite crucible be used for silver melting?
- Yes, a graphite crucible can be used for silver melting. Graphite is an excellent heat conductor and can withstand the high temperatures required for melting silver. It is also chemically inert, meaning it does not react with silver or contaminate the metal during the melting process.
