Other refractory materials for High temperature industry
- Q: Is graphite crucible resistant to hydrofluoric acid?
- The graphite crucible has a maximum temperature of 1800 degrees Celsius and can be used for a long time! But generally graphite crucibles are used below 1300 degrees celsius!
- Q: How do you determine the appropriate crucible depth for a specific application?
- To determine the appropriate crucible depth for a specific application, several factors need to be considered. Firstly, the type of material being melted or processed is crucial. Different materials have varying densities, melting points, and expansion properties, which influence the depth required for effective processing. For instance, materials with low melting points or high expansion rates may require a deeper crucible to accommodate the volume changes during heating. Secondly, the desired quantity of material to be processed is important. Larger quantities generally require deeper crucibles to ensure sufficient space for the molten material without overflowing or creating excessive turbulence during processing. Additionally, the heating method and equipment being used should be taken into account. Some heating methods, such as induction or resistance heating, may require specific crucible depths to optimize heat transfer and uniformity. The dimensions and specifications of the heating equipment also play a role in determining the appropriate crucible depth. Furthermore, the desired processing conditions and requirements should be considered. Factors such as desired mixing, stirring or agitation, temperature gradients, or the need for controlled cooling may influence the crucible depth. These requirements should be evaluated to ensure that the chosen crucible depth can fulfill the specific application's needs. Lastly, safety considerations and practical limitations should be taken into consideration. The crucible depth should be chosen to prevent any potential hazards, such as overflowing or splashing of molten material, and to ensure ease of handling and accessibility for loading and unloading. Overall, determining the appropriate crucible depth for a specific application requires assessing the material properties, processing requirements, heating method, and equipment specifications, while considering safety and practical limitations. It is advisable to consult relevant literature, equipment manufacturers, or experienced professionals to ensure an accurate determination of the crucible depth for optimal performance and safety.
- Q: Can industrial induction furnaces heat graphite?
- Graphite, though conductive, is not a metal. It seems that it doesn't conduct magnetism, so it seems infeasible to heat the graphite directly in an industrial induction cooker.
- Q: How do you determine the melting capacity of a graphite crucible?
- The melting capacity of a graphite crucible can be determined by considering its volume and the material it is made of. The volume of the crucible can be measured accurately, and it is essential to ensure that it is not overloaded beyond its capacity. The melting capacity also depends on the quality and purity of the graphite material used in the crucible. Higher-quality graphite crucibles can withstand higher temperatures and have a greater melting capacity compared to lower-quality ones. Therefore, it is crucial to refer to the manufacturer's specifications or consult experts to determine the melting capacity of a graphite crucible accurately.
- Q: Can graphite crucibles be used for thermal analysis?
- No, graphite crucibles are not typically used for thermal analysis. Graphite crucibles are mainly used for high temperature applications such as melting and casting metals, as well as for chemical reactions that require high heat. In thermal analysis, different techniques are used to study the physical and chemical properties of materials as they undergo changes in temperature. These techniques include differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and thermal conductivity measurements, among others. For these types of analyses, specialized equipment and materials are required. Typically, ceramic or metal crucibles are used as they have better thermal conductivity and stability at high temperatures, ensuring accurate and reliable measurements. These crucibles are designed to withstand thermal cycling and provide a controlled environment for the sample being analyzed.
- Q: Is it often influenced by graphite tube replacement in atomic absorption furnace?
- Graphite furnace atomic absorption spectrometry (AAS) is a kind of atomizer made of graphite material, such as tube, cup and so on. It is analyzed by atomic absorption spectrometry by current heating atomization. The sensitivity of the analysis has been greatly improved since all the samples participate in atomization and avoid dilution of atomic concentration in flame gas. The method is used for the determination of trace metals and is superior in performance to many other methods and can be used for the analysis of small amounts of samples and for direct analysis of solid samples. Therefore, it has a wide range of applications.
- Q: Where is the difference between the silicon carbide crucible and the graphite crucible?
- Where is the difference between the silicon carbide crucible and the graphite crucible?Silicon carbide crucibles can be used instead of graphite crucibles.
- Q: Can graphite crucibles be used for melting composite materials?
- Indeed, composite materials can be melted using graphite crucibles. Renowned for their elevated melting point and excellent thermal conductivity, graphite crucibles are well-suited for the fusion of various materials, including composite ones. Moreover, their resistance to chemical reactions renders them optimal for managing and confining composite materials while undergoing the melting procedure. Nevertheless, it is crucial to thoroughly assess the composite material's specific composition and melting point to guarantee its compatibility with the graphite crucible.
- Q: Graphite crucible used six or seven times on how bad?
- And the solution in the barrier, is it right?. The main check temperature should not be too fast, rapid cooling.
- Q: Graphite electrode, high temperature resistant oxidation coating, formulation technology
- Technology first, graphite crucible, anti-oxidation coating, water inorganic environmental protection paint, no volatile substance at high temperature and normal temperature. ZS-1021 Weihuanai closed high temperature coating itself with acid and alkali, the quenching medium of any reaction, chemical reaction can effectively protect the graphite crucible under high temperature, can effectively prevent the graphite crucible in high temperature oxidation rate reached more than 95%.
