Company Information
- Q: How to reduce the degree of oxidation of graphite when sintering at high temperature?
- Classification and cleaning of waste miscellaneous graphite plate, and the large burden burden with large surface area is packed in a press;
- Q: New energy, crystal, silicon and other research and development, production, because the crucible rotary table heating device, there is no good solution to share?
- 1. features:(1) according to the actual shape and size design, including 3 dimensional geometry to meet your equipment.(2) provide heater longer moisture antichemical silicone rubber material.(3) simple paste and touch on your parts, through vulcanization, adhesives, or fasten pieces, etc..
- Q: Can a graphite crucible be used for melting neptunium?
- No, a graphite crucible cannot be used for melting neptunium. Neptunium is a highly radioactive and pyrophoric element, meaning it spontaneously ignites in air. Graphite is not suitable for containing such reactive and hazardous materials. Instead, a specialized crucible made of a more resistant material, such as tantalum or platinum, would be required to safely melt neptunium. These materials have a higher melting point and are better equipped to handle the extreme conditions associated with neptunium.
- Q: Rotary kiln dust removal, zinc coated sand and Zinc Oxide Technology
- The use of Nianzi extracted from zinc in zinc,
- Q: How do you determine the appropriate crucible stirring rod for a specific application?
- To determine the appropriate crucible stirring rod for a specific application, one must consider several factors. Firstly, the type of material being stirred is important. Different materials may require specific types of stirring rods, such as those made of certain metals or alloys to prevent contamination or reactivity. Secondly, the size and shape of the crucible should be taken into account. The stirring rod should be long enough to reach the bottom of the crucible and have a suitable diameter for effective stirring. Additionally, the temperature and conditions of the application should be considered. High temperatures may require a stirring rod made of heat-resistant materials. Finally, any specific requirements or recommendations from the manufacturer or scientific literature should be followed to ensure the appropriate crucible stirring rod is chosen for the specific application.
- Q: Can graphite crucibles be used for ceramic production?
- No, graphite crucibles cannot be used for ceramic production. Ceramic production requires crucibles made from materials like alumina or zirconia, which can withstand high temperatures and provide a stable environment for the ceramic materials. Graphite crucibles are generally used for high-temperature applications involving metals and alloys.
- Q: What is the conductivity of graphite and copper, iron and zinc?
- Graphite and copper, iron, and zinc are electrically conductive. The conductivity and thermal conductivity are different for different grades of materials.
- Q: Is it possible to repair a cracked or damaged graphite crucible?
- No, it is not possible to repair a cracked or damaged graphite crucible. Graphite is a brittle material and once it is cracked or damaged, it cannot be repaired. It is recommended to replace the crucible to ensure proper functionality and safety.
- Q: Why do laboratory crucibles use ceramics instead of glass?
- Because the glass has a softening temperature, and the temperature is below 1000 DEG C, therefore, made of glass crucible at high temperature when the heating crucible may be softening deformation, and the glass crucible should not contact with alkaline substances.
- Q: Can quartz ceramic crucibles instead of graphite crucibles?
- For the time being, I don't know what to replace. Since graphite was chosen, nothing else could be used.
