Q:What is the conductivity of graphite and the conductivity of graphite?
The conductivity and thermal conductivity are different for different grades of materials.
Q:Can the graphite crucible be rinsed with water?
When the graphite crucible is heated, it will burst. If you rinse it with water, you must bake for about 20 hours before you use it. When the pan is completely dry, it's best to bake about six Baidu at regular intervals.
Q:Why does China choose quartz crucible directly in the aspect of Czochralski silicon?
The oxygen in the quartz crucible can not be avoided, and other methods can be adopted to reduce oxygen.
Q:How long does the graphite crucible extend its service life?
Must grasp the correct way to use, do not cause unnecessary losses, such as not take good, did not put, broken, and this is a great pity.
Q:The biggest problem with graphite crucibles must be to use in a vacuum or a reducing atmosphere
So it won't do him any harm. He must be in the electric stove to prevent air from entering. The gas stove needs a blower to blow it, that's because he can burn out the air!
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
Corundum temperature limited, easily cracked at high temperature. But the chemical stability is good, do not use under vacuum. In contrast, corundum is much cheaper.
Q:Is the graphite oven heating evenly?
There are two kinds of heating methods for general atomic absorption graphite furnace. One is light control mode, the other is current control mode. The light control mode at the beginning of atomization, the temperature exceeds the set temperature, and when the graphite tube is aging, the temperature is more than that. Replace the current control heating up, you try. Or try with a graphite tube.
Q:What do diamond, graphite and C60 have in common?
The chemical properties of diamond and graphite is the same, because they are made of carbon _, but there are significant differences in their physical properties, the reason is the different arrangement of carbon atoms.
Q:What are the uses of graphite? What are the downstream products of graphite?
As refractory material: graphite and its products have the properties of high temperature resistance and high strength. They are mainly used in the metallurgical industry to make graphite crucibles. In the process of steelmaking, graphite is often used as a protective agent for steel ingots and lining of metallurgical furnaces
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. The relevant information from the supply of silicon carbide crucible dachengxian Tianjin high silicon carbide crucible crucible factory released using the latest international technology of isostatic pressing method and strict quality assurance inspection system, selection of high quality refractory raw materials, high-tech to develop a new generation of high quality silicon carbide crucible, this product has a large volume density, high temperature resistance, fast heat, acid and alkali resistance, high temperature strength, oxidation resistance and high service life is 3 times that of the clay graphite crucible.
