Welcome to visit our factory.


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 and excellent thermal conductivity, allowing it to withstand high temperatures and efficiently transfer heat to the alloy. Additionally, graphite is chemically inert and does not react with most metals, making it an ideal choice for melting low melting point alloys.
Q:What are the welding methods at the end of the thermocouple?
Salt welding type K thermocouple in the beaker into the sodium chloride solution into the platinum wire in aqueous solution as an electrode, and the electrode heat as another electrode. When soldering, contact the top of the thermocouple with the solution slightly, switch on the power supply and switch off the power quickly after the arc is started. This welding method is suitable for welding 0.03mm-0.3mm thermocouples with finer welding diameter.
Q:Is there a single crystal mine in nature? The purification technology and principle of graphite ore? Please detail, thank you!
There seems to be no pure monocrystalline silicon in nature.The order of silicon is: silicon dioxide ore - industrial silicon - polycrystalline silicon - monocrystalline silicon. Monocrystalline silicon is made from polycrystalline silicon by single crystal furnace, and it can also be used to prepare monocrystalline silicon by melting. However, the monocrystalline silicon has a large dislocation density, so the semiconductor device uses drawn monocrystalline silicon as raw material.
Q:How long can a graphite crucible last for a long time?
The special thermal shock resistance, thermal expansion of graphite is anisotropic, and the macro expansion coefficient is small, the temperature change under the condition that the volume change of graphite is not large, coupled with its good thermal conductivity, good thermal shock resistance and graphite.
Q:What are the different methods of monitoring the melting process in a graphite crucible?
There are several methods of monitoring the melting process in a graphite crucible, including visual inspection, thermocouple temperature measurement, pyrometry, and spectroscopy. Visual inspection involves observing the melting material through a transparent cover or window to assess its state. Thermocouples can be used to measure the temperature directly at different points in the crucible, providing real-time temperature data. Pyrometry utilizes infrared radiation to measure the temperature of the molten material. Spectroscopy involves analyzing the emitted light or radiation from the melting material to determine its composition and temperature.
Q:Can a graphite crucible be used for laboratory applications?
Laboratory applications can indeed utilize a graphite crucible. These crucibles, widely employed in laboratories, serve a multitude of purposes such as heating, melting, and substance analysis. Their exceptional thermal conductivity, ability to withstand extreme temperatures, and chemical inertness render them appropriate for managing and containing high-temperature materials. Graphite crucibles find common use in activities such as determining melting points, fusing samples for analysis, and acting as receptacles for reactions involving intense heat or corrosive substances. Nonetheless, it is crucial to recognize that the appropriateness of a graphite crucible for a given laboratory application may rely on factors including the nature of the substances being handled, the required temperature range, and the specific conditions of the experiment.
Q:What are the components of a pencil core?
The main component of graphite C, he is an allotrope of carbon.
Q:What material does the crucible belong to?
The crucible is to use a very refractory materials (such as clay, graphite, kaolin, quartz or difficult to molten metal such as iron) made of the vessel or melting tank
Q:Can graphite crucibles be used for melting refractory metals?
Yes, graphite crucibles can be used for melting refractory metals. Graphite crucibles have a high melting point and excellent resistance to heat, making them suitable for use in high-temperature applications such as melting refractory metals. Additionally, graphite crucibles offer good thermal conductivity, chemical inertness, and low thermal expansion, which makes them an ideal choice for melting and casting refractory metals.
Q:Graphite electrode, high temperature resistant oxidation coating, formulation technology
Graphite materials synthetic materials under high temperature including graphite electrode, graphite mold and graphite crucible three, these three kinds of materials of graphite under high temperature, the graphite is prone to oxidation combustion reaction, cause the rubber surface material of carbon layer porosity increase and loose structure, influence the service life. Taking the conventional baking process of the ladle as an example, the surface of the carbon containing (graphite) refractory material is produced more than 15mm after being roasted, and the decarburization layer is eroded rapidly after being filled. The majority of graphite crucible using ZS-1021 high temperature resistant sealing coating, the coating with high temperature resistance, Sheng Chi Wei Hua special high temperature solution, temperature can reach 1800 DEG C, can long time open flame barbecue, coating materials with nano scale lamellar structure, good compactness, effectively prevent the diffusion of oxygen at high temperature, the hardness can reach 7-8H and the hardness is higher than the hardness of metals. Zhi Sheng Wei Hua ZS-1021 high temperature resistant coating paint closed dense coating formed on the graphite crucible, with strong anti corrosion resistance, high temperature oxidation, anti discoloration effect, resistant properties. High temperature resistant sealing coating is applied to kiln, graphite, metal and so on. At the high temperature, the oxidation rate can reach more than 80%, and the energy saving efficiency of graphite crucible material can reach more than 95%.
