- Q:Are there any special precautions to be taken while using graphite crucibles?
- While using graphite crucibles, it is essential to take special precautions into consideration. Careful handling is crucial as these crucibles are delicate and prone to breakage. To prevent cracks or damage, it is important to avoid dropping or mishandling them. Furthermore, storing graphite crucibles in a clean and dry environment is necessary to prevent contamination. Impurities from the surroundings can be absorbed by graphite, impacting its performance and durability. Hence, maintaining a contamination-free storage space is advised. To avoid thermal shock, which can cause cracks or breakage, it is crucial to refrain from subjecting graphite crucibles to sudden temperature changes. Gradually heating or cooling the crucible within the recommended temperature range is recommended to prevent thermal shock. Prior to initial use, it is important to properly season or preheat the graphite crucible. This process involves slowly heating the crucible to a specific temperature to eliminate any moisture or volatile substances present. Neglecting to season the crucible appropriately can result in cracking or premature failure during subsequent use. Additionally, it is vital to avoid overloading the crucible with excessive material, as graphite crucibles have specific capacity limits. Overloading can lead to crucible failure or reduce its lifespan. Lastly, when handling molten materials or pouring them into the crucible, it is essential to wear suitable personal protective equipment. This includes heat-resistant gloves, face shields, and other protective clothing to prevent burns or injuries. By adhering to these precautions, users can ensure the safe and effective use of graphite crucibles while maximizing their lifespan and performance.
- Q:Corundum crucible and graphite crucibleSome enterprises use graphite crucibles in vacuum furnaces, while some larger ones use corundum crucibles. What I want to know is the advantages and disadvantages of corundum crucibles and graphite crucibles
- Graphite crucible is a high temperature resistant and difficult to sinter material. But the biggest problem must be used in vacuum or reducing atmosphere. Otherwise, graphite is easily oxidized at high temperature. Moreover, this crucible is more expensive
- Q:What are the different methods of preventing graphite crucible leakage?
- There are several methods to prevent graphite crucible leakage. One common method is to use high-quality graphite material with low porosity, which reduces the chances of leakage. Applying a suitable coating or sealant on the crucible's inner surface can also help prevent leakage. Additionally, ensuring proper installation and tight sealing of the crucible lid or cover is crucial. Regular maintenance and inspection of the crucible, including checking for any cracks or damage, can help detect and prevent leakage early on.
- Q:Can a graphite crucible be used for melting thorium?
- No, a graphite crucible cannot be used for melting thorium. Thorium has a high melting point, and its reactivity with graphite can cause contamination and reaction with the crucible material. A suitable crucible made from materials like ceramic or refractory metals should be used for melting thorium.
- Q:Can waste circuit boards be recycled?
- The waste circuit board can be recycled, the PCB circuit board plating waste liquid has greater recycling value, and the PCB circuit board plating waste liquid can be saved on the comprehensive utilization, and the cost can be saved and the cost can be reduced. The comprehensive utilization of PCB plating waste liquid is not only to reduce the losses caused by the discharge, but also is of great significance from the angle of preventing pollution and reducing the cost of sewage treatment.
- Q:The difference between single graphite furnace graphite furnace atomic absorption spectrophotometer and double graphite furnace
- Flame atomizer: it consists of three parts: sprayer, premixing chamber and burner. Features: easy operation and good reproducibility.Graphite furnace atomic device is a type of system will be placed in the pipe wall, graphite platform, carbon sample holes or graphite crucible with electric heating to a high temperature to achieve atomization. Tubular graphite furnace is the most commonly used atomization device.The atomization program is divided into drying, ashing, atomization and high temperature purificationThe atomization efficiency is high: under the adjustable high temperature, the sample utilization rate is 100%High sensitivity: the detection limit is 10-6~10-14Small amount of sample: suitable for determination of refractory elements
- Q:Can a graphite crucible be used for melting rare earth metals?
- Yes, a graphite crucible can be used for melting rare earth metals. Graphite is a suitable material for high-temperature applications, and it has good resistance to chemical reactions with various elements, including rare earth metals.
- Q:Can graphite crucibles be used for melting food-grade materials?
- No, graphite crucibles should not be used for melting food-grade materials. Graphite is a form of carbon that can release impurities or contaminants when exposed to high temperatures. These impurities can be harmful if ingested or come into contact with food. It is recommended to use food-grade materials such as stainless steel or ceramic for melting food-grade materials to ensure the safety and quality of the end product.
- Q:Can graphite crucibles be used for metal powder atomization?
- Yes, graphite crucibles can be used for metal powder atomization. Graphite crucibles are commonly used in metallurgical processes due to their high thermal conductivity, chemical inertness, and resistance to high temperatures. In metal powder atomization, the crucible is heated to a high temperature, and the metal feedstock is melted and then atomized into fine powder particles using a gas or water jet. The graphite crucible helps to maintain a stable temperature during the atomization process and allows for efficient heat transfer, resulting in consistent and high-quality metal powder production. Additionally, graphite crucibles can withstand the corrosive nature of molten metals, making them suitable for various metal powder atomization applications.
- Q:How to judge the thermal stability of rubber oil?
- 1.2 sample containers, crucibles, aluminium crucibles, copper crucibles, platinum crucibles, graphite crucibles, etc. shall not react with specimens and reference materials. 1.3 air source, air, nitrogen and so on, the purity should reach the purity of industrial gas. 1.4 the cooling temperature of the cooling device of the cooling device should be up to -50 degrees centigrade. No enthalpy change occurs in the range of test temperature of 1.5 reference substance. Typical reference materials are calcined alumina, glass beads, silicone oil, or empty containers. Store in a dryer.
