Q:Which is a good quality graphite crucible?

Because the bottom of the pot is very small, it usually needs to be placed on the clay triangle to heat it directly. The crucible can be placed on the iron tripod with either positive or oblique directions, and can be placed on the basis of the requirements of the experiment. When the crucible is heated, it cannot be immediately placed on a cold metal table to prevent it from breaking due to rapid cooling. It should not be placed on the wooden table immediately so as not to spoil the table or cause fire. The correct method is to cool the metal on the tripod or to let it cool slowly on the asbestos net. For crucible purposes, see the crucible tongs.

Q:Single crystal furnace quartz crucible cast 22 inch 175 kilograms of feed it

Back chaos, in fact we are very worried about the recovery of this material strength and composition by crucible crucible change can not be used, but also fast, so the results will soon be out.

Q:How does the erosion resistance of graphite affect the performance of a crucible?

The erosion resistance of graphite plays a significant role in determining the performance of a crucible. Graphite is known for its excellent erosion resistance, which refers to its ability to withstand the wearing away or gradual destruction caused by various factors such as heat, chemicals, and mechanical forces. In the context of a crucible, which is a vessel used for melting and holding substances at high temperatures, erosion resistance is crucial for maintaining the integrity and longevity of the crucible. The erosion resistance of graphite ensures that the crucible can withstand the harsh conditions it is exposed to during the melting process. Firstly, the erosion resistance of graphite helps to prevent the crucible from deforming or cracking under high temperatures. Graphite has a high melting point and can withstand extreme heat, which makes it an ideal material for crucibles. Without erosion resistance, the crucible would be prone to thermal shock, resulting in cracking or failure. Secondly, erosion resistance is important for preserving the chemical stability and purity of the crucible. Graphite is chemically inert, meaning it does not react with most substances. This property allows the crucible to hold a wide range of materials without the risk of contamination. Additionally, the erosion resistance of graphite ensures that there is minimal loss of graphite particles into the molten materials, preventing impurities from being introduced into the final product. Furthermore, the erosion resistance of graphite contributes to the crucible's durability and overall performance. Graphite crucibles are often subjected to mechanical stresses, such as stirring or pouring of molten substances. The erosion resistance of graphite prevents the crucible from wearing away or deteriorating over time, ensuring that it can be used repeatedly without compromising its functionality. In summary, the erosion resistance of graphite is crucial for the performance of a crucible. It helps to maintain the structural integrity, withstand high temperatures, preserve chemical stability, and enhance the durability of the crucible. Without erosion resistance, the crucible would be prone to failure, leading to potential contamination, loss of material, and reduced lifespan.

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:Can graphite crucibles be used with gas-fired furnaces?

Yes, graphite crucibles can be used with gas-fired furnaces. Graphite is a suitable material for high-temperature applications and is commonly used in furnaces, including gas-fired ones, due to its excellent heat resistance and thermal conductivity properties.

Q:What are the different methods of monitoring the melting process in a graphite crucible?

There are several methods of monitoring the melting process in a graphite crucible, including visual inspection, thermocouple temperature measurement, pyrometry, and spectroscopy. Visual inspection involves observing the melting material through a transparent cover or window to assess its state. Thermocouples can be used to measure the temperature directly at different points in the crucible, providing real-time temperature data. Pyrometry utilizes infrared radiation to measure the temperature of the molten material. Spectroscopy involves analyzing the emitted light or radiation from the melting material to determine its composition and temperature.

Q:How long will it take to warm the water at 20 degrees to 3000 degrees at 3800?

To calculate time, there must be heating power, heating methods, water quality and physical state. If a small drop of water is placed in a 2000C graphite crucible, the water instantly becomes vapour, and some of the water molecules are broken down into hydrogen and oxygen.

Q:Graphite crucible used six or seven times on how bad?

And the solution in the barrier, is it right?. The main check temperature should not be too fast, rapid cooling.

Q:What magnetic material is sintered with large corundum crucible?

But the chemical stability is good, not in vacuum. Corundum, by contrast, is much cheaper.
