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:Can graphite crucibles be used for laboratory analysis?: Yes, graphite crucibles can be used for laboratory analysis. Graphite is a commonly used material in laboratories due to its high temperature resistance and chemical inertness. It is especially useful for carrying out high-temperature processes, such as melting metals, as it can withstand temperatures up to 3000 degrees Celsius. Additionally, graphite crucibles have excellent thermal conductivity, allowing for even heat distribution during experiments. However, it is important to note that graphite crucibles may react with certain chemicals or elements under specific conditions, so it is crucial to consider the compatibility of the crucible material with the substances being analyzed. Furthermore, the choice of crucible material should also be based on the specific requirements of the analysis, as other materials like porcelain, quartz, or platinum may be more suitable in certain situations.

Q:Graphite is widely used in industry and in daily life. It can not be used in industry: Many devices for conveying corrosive media are made of graphite materials, piston cups, seals and bearings. They do not need to be lubricated when running. Graphite is many metal processing (drawing, drawing) the good lubricant.For the production of heat exchanger, reaction tank, condenser, combustion tower, absorption tower, cooler, heater, filter and pump equipment. Widely used in petroleum, chemical, hydrometallurgy, acid and alkali production, synthetic fiber, papermaking and other industrial sectors, can save a lot of metal materials.

Q:Can graphite crucibles be used for melting iron?: No, graphite crucibles cannot be used for melting iron as iron has a much higher melting point than graphite can withstand.

Q:Can a graphite crucible be used for melting magnetic materials?: Using a different grammatical structure and expressions: It is not possible to use a graphite crucible for melting magnetic materials. Graphite, being a non-magnetic substance, lacks the capacity to create or maintain a magnetic field. Consequently, it is unsuitable for melting magnetic materials as it cannot effectively engage with or confine them.

Q:What can replace a graphite crucible?: Installation of crucible:1. The crucible base (crucible station) requires the same crucible bottom diameter or greater height of the crucible platform to prevent fire from spraying into the crater above the crucible.2. Using refractory bricks, the crucible station shall be a round brick, flat without bending, and shall not be made of brick or semi - uniformly, preferably imported graphite crucibles.3. The unit is placed in a crucible melting, melting of the solution in the center, the coke powder, made of ash or refractory cotton mat, in order to avoid the crucible and crucible Taiwan rod, erected after the crucible, need to melt and the need for the central level (highest level ruler).4. The size of the crucible and furnace fit, the distance between the crucible and the molten wall, shall be suitable for at least 40mm.5. When the furnace crucible is installed, the gap in the gap below the contact brick, the crucible should be set aside about 30-50MM dollars gap, not the bottom pad, things, mouth and smooth cotton, refractory material, furnace wall. Requires a fixed furnace wall, refractory bricks, thermal expansion, space heating after the required corrugated cardboard, 3mm thick pad crucible.

Q:How to reduce the degree of oxidation of graphite when sintering at high temperature?: Strict control of the smelting temperature to prevent overheating, flame injection should have a certain angle, in order to quickly melt, shorten the melting time;

Q:How does a graphite crucible handle abrasion resistance?: A graphite crucible has excellent abrasion resistance due to the unique properties of graphite.

Q:How does the gas permeability of graphite affect crucible performance?: The gas permeability of graphite plays a crucial role in determining the performance of a crucible. Graphite is known for its excellent gas permeability, meaning it allows gases to pass through it easily. This property is advantageous in a crucible because it allows for the escape of gases that may be generated during high-temperature processes, such as melting or heat treatment. When a crucible is exposed to high temperatures, various chemical reactions may occur, leading to the production of gases such as carbon dioxide or carbon monoxide. If these gases are trapped within the crucible, they can create pressure build-up, causing the crucible to crack or even explode. However, with the gas permeability of graphite, these gases can escape through the crucible walls, preventing any potential damage. Moreover, the gas permeability of graphite also aids in the removal of impurities or volatile substances from the crucible. During certain processes, impurities or volatile materials may be present in the material being melted or treated. If these substances are not allowed to escape, they can contaminate the final product or affect the quality of the process. The gas permeability of graphite allows for the easy removal of these impurities, ensuring a cleaner and more efficient process. Overall, the gas permeability of graphite is essential for crucible performance as it enables the safe release of gases generated during high-temperature processes and facilitates the removal of impurities. By allowing gases to escape and preventing pressure build-up, graphite crucibles can maintain their structural integrity and durability. Additionally, the gas permeability of graphite promotes cleaner processes and ensures the quality of the final product.

Q:Is the silicon carbide crucible good for use? What's the difference between an ordinary graphite crucible and a graphite crucible?: Easy to use and convenient.The ordinary graphite crucible can not guarantee the safety in the high temperature environment, moreover, the conduction speed is slow in the test, which is not good for the experiment.
