- Q:Graphite and diamond are elemental elements made of carbon. Why are physical properties so different?
- diamondDiamond is pure carbon, graphite and chemical properties are basically the same, but the physical properties are not the same. The diamond carbon atoms is a tetrahedral solid, a Pyramid shaped structure, the overall shape of the crystal was eight, the structure is very stable, which leads to the hardness of diamond is very high. In addition to diamond almost non-conductive, hard material is the most natural, it is of poor thermal conductivity, high melting point, colorless and transparent.
- Q:What are the different accessories available for graphite crucibles?
- Graphite crucibles can be enhanced and made more suitable for specific applications by utilizing a range of accessories. Some commonly used accessories include: 1. Utilizing long-handled crucible tongs ensures safe handling of hot crucibles, offering a secure grip and preventing accidental burns or spills. 2. The addition of crucible covers provides protection against contamination or oxidation, maintaining a controlled environment within the crucible and preserving the purity of the materials being heated or melted. 3. Crucible holders offer stability during heating or pouring, preventing the crucible from tipping over or spilling its contents. 4. Crucible racks serve as storage holders, promoting organization and preventing accidental damage or breakage when the crucibles are not in use. 5. Crucible stirrers assist in achieving a uniform distribution of temperature and homogeneity of the molten material, facilitating melting or mixing processes. 6. To clean graphite crucibles after use, specialized tools such as brushes, scrapers, or solvents designed specifically for graphite crucibles can be utilized. 7. In addition to covers, specialized lids can be used to tightly seal the crucible during certain applications, creating a controlled atmosphere or preventing the escape of volatile substances. 8. Crucible lifters are designed to safely transport hot crucibles from one location to another, withstanding high temperatures and providing a secure grip. 9. The use of insulating materials like ceramic fiber blankets or jackets can provide additional thermal insulation, maintaining a consistent temperature and preventing heat loss. 10. Ceramic or refractory liners can protect graphite crucibles from chemical reactions or erosion caused by aggressive materials or corrosive environments. These accessories offer a range of advantages and options to optimize the performance and utilization of graphite crucibles based on specific requirements and applications.
- Q:How do you determine the appropriate crucible diameter for a specific application?
- The appropriate crucible diameter for a specific application is typically determined by considering factors such as the desired sample size, the melting or reaction temperature, the thermal conductivity of the material being heated, and the available heating equipment. Additionally, the crucible should have sufficient room for the sample to expand during heating without overflowing. It is important to consult relevant literature, technical specifications, or seek expert advice to ensure the appropriate crucible diameter is selected for the specific application.
- Q:Why can't a f containing compound be used in a porcelain crucible, a Lilac Garden?
- The F containing compound can not be used in the ceramic crucible for combustion and drying. The main reason is that the corrosion of fluorine on porcelain at high temperature.
- Q:Are graphite crucibles suitable for melting alloys with low melting points?
- Yes, graphite crucibles are suitable for melting alloys with low melting points. Graphite has a high melting point, excellent thermal conductivity, and is chemically inert, making it an ideal material for use in high-temperature applications such as melting metals and alloys. Graphite crucibles can withstand the high temperatures required to melt alloys with low melting points without cracking or deforming. Additionally, graphite crucibles have good heat retention properties, allowing for efficient and uniform heating of the alloy. Therefore, graphite crucibles are commonly used in industries such as metallurgy and foundries for melting alloys with low melting points.

- Q:How to improve the service life of graphite crucible
- 1. Adopt isostatic graphite material;2. Use in a vacuum or inert atmosphere;3, prevent cold, hot;4. Avoid melting material with crucible reaction;5, the structural design rationalization.
- Q:Can graphite crucibles be used for plasma arc melting?
- Yes, graphite crucibles can be used for plasma arc melting. Graphite has excellent heat resistance and electrical conductivity properties, making it suitable for containing and melting materials under high temperatures generated by plasma arcs.
- Q:Melting the iron in the graphite crucible. Does the graphite in the crucible turn into carbon and it melts into the steel?
- Graphite is a very pure substance, and graphite is a transition crystal. The carbon atoms in each layer of graphite are bonded by non-polar covalent bonds, and the molecular layers of graphite are joined by intermolecular forces. The melting point of the graphite crucible is 3652 to 3697 degrees (sublimation), so the graphite crucible is high temperature resistant.
- Q:Can a graphite crucible be used for melting food-grade substances?
- No, a graphite crucible should not be used for melting food-grade substances as graphite can react with the food and contaminate it. It is important to use food-grade materials specifically designed for heating and melting food substances.
