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:Can graphite crucibles be used for carbonization processes?: Carbonization processes can make use of graphite crucibles. Graphite is highly suitable for applications that involve high temperatures because of its exceptional thermal conductivity and resistance to thermal shock. Graphite crucibles are frequently employed in carbonization processes, where carbon-rich materials are heated to high temperatures without the presence of oxygen. These crucibles effectively contain and heat the materials. Graphite's high thermal conductivity ensures efficient transfer of heat, resulting in uniform heating and minimal heat loss. Furthermore, graphite's resistance to thermal shock enables it to withstand sudden temperature changes that occur during the carbonization process. In conclusion, graphite crucibles are a dependable and appropriate choice for carbonization processes.

Q:Can graphite crucibles be used for carbon and graphite production?: Yes, graphite crucibles can be used for carbon and graphite production. Graphite crucibles are made from high-purity graphite and are designed to withstand high temperatures and chemical reactions. They have excellent thermal conductivity and can resist thermal shock, making them ideal for applications such as carbon and graphite production. These crucibles can be used in various processes, including melting and refining of carbon and graphite materials. Additionally, graphite crucibles can be reused multiple times, making them a cost-effective choice for carbon and graphite production.

Q:Why is the crucible burned and then black, oxidized, chemically?: If the crucible is heated by an alcohol lamp, the black substance, which is the main component of the black substance after the fire has been burned, is one of the carbon elements, chemically called C., which is produced by incomplete combustion of alcohol

Q:Can a graphite crucible be used for ceramic molding?: Using a graphite crucible for ceramic molding is not possible. Graphite crucibles are mainly designed for melting and holding metals and alloys at high temperatures. They lack the necessary properties to endure the high temperatures required for ceramic firing and molding procedures. The firing process in ceramic molding usually involves temperatures ranging from 1000 to 1600 degrees Celsius, which can result in the degradation, cracking, or melting of graphite crucibles. To successfully carry out ceramic molding, it is advisable to utilize crucibles made from materials like alumina, zirconia, or other refractory substances that can withstand the extreme temperatures involved in the ceramic firing process.

Q:Can graphite crucibles be used for catalyst preparation?: Yes, graphite crucibles can be used for catalyst preparation. Graphite crucibles are often used in high temperature applications due to their excellent thermal conductivity and resistance to thermal shock. They can withstand temperatures up to 3000°C, making them suitable for various catalyst preparation processes that involve high temperatures. Graphite crucibles provide a stable and inert environment for catalyst synthesis and preparation. They do not react with most chemicals, making them compatible with a wide range of catalyst materials and precursors. This allows for effective catalyst synthesis without the risk of impurities or unwanted reactions. Furthermore, graphite crucibles are known for their durability and long lifespan, which makes them cost-effective for repeated use in catalyst preparation. They can be easily cleaned and reused, reducing the overall cost of the catalyst preparation process. It is worth noting that the choice of crucible material may depend on the specific catalyst preparation process and the chemicals involved. While graphite crucibles are generally suitable for many catalyst preparation applications, some highly reactive or corrosive chemicals may require the use of alternative crucible materials, such as ceramic or quartz crucibles. Therefore, it is important to consider the specific requirements of the catalyst preparation process before selecting a crucible material.

Q:Can a graphite crucible be used for iron melting?: No, a graphite crucible cannot be used for iron melting. Iron has a higher melting point compared to graphite, and it requires a crucible made of a material that can withstand the high temperatures and chemical reactions involved in iron melting, such as a clay or silicon carbide crucible.

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:Is the yellow metal in the graphite rock gold?: It would be more convenient if we could find the touchstone. From the proportion can be simply measured, the proportion of gold is very large.

Q:Graphite electrode, high temperature resistant oxidation coating, formulation technology: In the high temperature induction heating graphite crucible, graphite electrode used in high temperature oxidation environment will occur due to the high temperature arc part sublimation oxidation, will cause the continuous consumption of graphite crucible, even broken, broken. The graphite crucible loss rate will reach 40-60%. Zhi Sheng years of research production Wei Hua ZS high-temperature sealing paint is mainly used in high temperature environment protection against oxidation of graphite electrode, graphite crucible, graphite products, slow oxidation rate, increase the strength of the material, improve the service life. The fracture rate of graphite electrode is lower than that of graphite electrode.
