- Q: Can a graphite crucible be used for gold melting?
- Indeed, gold melting can be accomplished by utilizing a graphite crucible. Graphite crucibles find extensive application in diverse sectors, such as jewelry fabrication and metal casting, owing to their remarkable thermal conductivity and elevated melting point. Graphite exhibits exceptional resilience against extreme temperatures, rendering it appropriate for gold melting, given that gold possesses a comparably moderate melting point of approximately 1064 degrees Celsius (1947 degrees Fahrenheit). Furthermore, graphite crucibles exhibit no reaction with molten gold, thus guaranteeing the preservation of gold purity throughout the melting procedure.
- Q: Can graphite crucibles be used for semiconductor manufacturing?
- No, graphite crucibles cannot be used for semiconductor manufacturing.
- Q: In the melting of aluminum alloys, what is the frequency furnace and the crucible type furnace? I heard that the frequency furnace power is lower, faster and more power saving
- If the use of neutral sand lining, the service life will be many, usually in 230 or more before changing the furnace lining.
- Q: Can graphite crucibles be used for melting bronze?
- Yes, graphite crucibles can be used for melting bronze. Graphite crucibles are commonly used in foundries and other metalworking industries because graphite has a high melting point and excellent thermal conductivity. These properties make graphite crucibles suitable for melting various metals, including bronze. Bronze typically melts at temperatures around 950°C (1742°F), which is well within the capabilities of graphite crucibles that can withstand temperatures up to 3000°C (5432°F). Furthermore, graphite crucibles have good resistance to chemical reactions with molten metals, ensuring that the crucible does not contaminate the bronze during the melting process. Therefore, graphite crucibles are a reliable and popular choice for melting bronze and other metals.
- Q: How do you use crucibles to process copper?
- The medium frequency furnace crucible is made of quartz sand lining material, and the crucible has a long service life, usually in three months. The power frequency furnace is also sintered with quartz sand.
- Q: Graphite grinding out of soy milk foam, how to foam?
- Generally speaking, plant seeds contain more phospholipids, such as soybeans and seeds. Most phospholipids are insoluble in water (freshly made soybean milk contains foam or phospholipids)
- Q: Can graphite crucibles be used for metal powder sintering?
- Indeed, metal powder sintering can be accomplished using graphite crucibles. The utilization of graphite as crucible material is widespread owing to its elevated melting point, chemical inertness, and thermal conductivity. The process of metal powder sintering entails subjecting the powder to intense heat in order to fuse the particles together, and graphite crucibles possess the capability to withstand such high temperatures without undergoing any reaction with the metal powders. Moreover, the commendable thermal conductivity of graphite crucibles facilitates the even distribution of heat, thereby ensuring the uniform sintering of the metal powder. Consequently, graphite crucibles are an appropriate choice for carrying out metal powder sintering procedures.

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: What are the different methods of sealing a graphite crucible?
- There are several methods of sealing a graphite crucible, each with its own advantages and considerations. One common method is the use of a graphite cement or adhesive. This involves applying the cement or adhesive to the joints or seams of the crucible and allowing it to dry or cure. The advantage of this method is that it forms a strong and durable seal, ensuring that the crucible remains tightly sealed during high-temperature applications. However, it can be time-consuming and may require periodic reapplication to maintain the seal. Another method is the use of a graphite crucible cover or lid. This involves placing a lid or cover on top of the crucible to create a seal. The advantage of this method is that it is relatively quick and easy to implement. However, it may not provide as tight of a seal as other methods, and care must be taken to ensure that the lid or cover is properly aligned and fitted to the crucible. Some crucibles may also be sealed using a combination of mechanical fasteners, such as bolts or clamps, and a high-temperature gasket material. This method involves securing the crucible joints using the fasteners and then applying a gasket material to create a tight seal. The advantage of this method is that it provides a reliable and secure seal, even under high-temperature conditions. However, it may require additional time and effort to install and remove the fasteners and gasket material. It's important to note that the specific method of sealing a graphite crucible may depend on the specific application and requirements. Factors such as the operating temperature, duration, and type of material being processed should be taken into consideration when selecting the appropriate sealing method. Additionally, it is recommended to consult the manufacturer's guidelines and instructions for the specific crucible being used to ensure proper sealing techniques are followed.
- Q: Can graphite crucibles be used for melting organic materials?
- Yes, graphite crucibles can be used for melting organic materials. Graphite is known for its high melting point and excellent thermal conductivity, making it a suitable material for high-temperature applications. When melting organic materials, such as polymers or organic compounds, it is important to use a crucible that can withstand the high temperatures without reacting or contaminating the material. Graphite is chemically inert and does not react with most organic substances, making it an ideal choice for melting organic materials. Additionally, graphite crucibles are typically designed to have good thermal shock resistance, allowing them to withstand rapid temperature changes during the melting process. Overall, graphite crucibles are commonly used in various industries, including chemistry and metallurgy, for melting organic materials due to their excellent heat resistance and chemical inertness.
