Sic Graphite Crucible

Q:What is the use of an iron crucible?: When solids have to be heated by fire, the crucible must be used.

Q:How do you prevent graphite crucibles from sticking to the melted material?: One way to prevent graphite crucibles from sticking to the melted material is by applying a suitable release agent or coating to the surface of the crucible. This can create a barrier between the crucible and the melted material, preventing them from adhering to each other. Additionally, maintaining proper temperature control and ensuring the crucible is properly preheated before adding the melted material can also help minimize sticking.

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!: If the intermediate frequency furnace may smelt, pays attention to the coating, will cross several furnaces to have to paint once.The alloy after melting also needs to be transferred to the heat preservation furnace, and then the slag removal and degassing are carried out. Because of the rotation of the aluminum liquid in the intermediate frequency furnace, the separation effect of slag inclusion is very poor.

Q:To sum up the different uses (and causes) of various crucibles in ChemistryQuartz glass crucibles, for examplealumina crucibleGlass crucibles, iron crucibles, and the like are different and should be noted: The quartz glass crucible can be used in the 1450 degrees below two points, transparent and opaque. With translucent quartz crucible arc method is drawing large diameter silicon based material is essential to the development of large scale integrated circuits. Nowadays, the semiconductor industry in the world developed countries have used the crucible instead of transparent quartz crucible is small. He has high purity, resistance strong heat, large size high precision, good heat insulation, energy saving, stable quality and other advantages.

Q:What are the recommended storage conditions for graphite crucibles?: To ensure optimal storage conditions for graphite crucibles, it is recommended to keep them in a cool, dry, and clean environment. It is important to store these crucibles in a space with controlled temperature, ensuring that it does not exceed 50 degrees Celsius (122 degrees Fahrenheit). It is crucial to avoid exposing them to extreme temperatures, as excessive heat may lead to oxidation or degradation of the graphite material. Moreover, it is essential to keep the crucibles away from any sources of moisture or humidity, as water can react with the graphite and compromise its structural integrity. To prevent contamination, it is advisable to store the graphite crucibles separately from other materials and make sure they are not in contact with any corrosive substances. Regularly cleaning and inspecting the crucibles before storing them can also aid in maintaining their quality and prolonging their lifespan.

Q:How to improve the service life of graphite crucible: From the product point of view:1., raw materials are chosen from natural graphite to ensure that the graphite is not easily oxidized;2. cold isostatic pressing process is adopted to ensure high density and strength of crucible;3., the crucible surface high temperature, low temperature protection glaze layer, isolated oxygen and graphite contact contact;From the production point of view:1., scientific warming, to prevent cold, hot;2. add proper and proper amount of refining agent;3. do not stop the furnace abnormally;

Q:How does the reactivity of graphite affect the performance of a crucible?: The reactivity of graphite directly affects the performance of a crucible. Graphite is known for its low reactivity and high thermal conductivity, making it an excellent material for crucibles. Its low reactivity means that it does not easily react with the substances being melted or heated inside the crucible, ensuring that the purity of the materials is maintained. This is particularly important in applications such as chemical analysis and metallurgy, where maintaining the integrity of the sample is crucial. Furthermore, the high thermal conductivity of graphite allows for efficient heat transfer, ensuring that the heat is evenly distributed throughout the crucible. This property helps in achieving uniform heating and melting of substances inside the crucible, leading to consistent and accurate results. In addition to its low reactivity and high thermal conductivity, graphite also has a high melting point, making it capable of withstanding high temperatures without deforming or breaking. This is essential for applications that involve high-temperature processes, such as melting metals or performing high-temperature chemical reactions. Overall, the reactivity of graphite plays a vital role in the performance of a crucible by ensuring the purity of the substances being heated, facilitating efficient heat transfer, and withstanding high temperatures.

Q:Medium frequency furnace plus graphite crucible does not start: Hello, my factory is specializing in the production of graphite crucible manufacturers, medium frequency furnace dedicated graphite crucible and so on

Q:What are the different methods of measuring the temperature inside a graphite crucible?: There are several methods for measuring the temperature inside a graphite crucible. One common method is using a thermocouple, which is a device that measures temperature by measuring the voltage difference between two different metals. Another method is using an infrared (IR) thermometer, which measures temperature by detecting the infrared radiation emitted by the crucible. Additionally, some crucibles have built-in temperature sensors or probes that can directly measure the temperature.

Q:Can a graphite crucible be used for titanium melting?: It is not possible to use a graphite crucible for melting titanium. The melting point of titanium is extremely high, reaching 1,668 degrees Celsius (3,034 degrees Fahrenheit), surpassing the maximum temperature capability of graphite, which is approximately 3,000 degrees Celsius or 5,432 degrees Fahrenheit. Consequently, if a graphite crucible were employed for titanium melting, the crucible would degrade and potentially pollute the titanium. In lieu of this, a crucible composed of materials like zirconium or ceramic should be utilized for titanium melting, as they can endure the elevated temperatures necessary for the procedure.
