Graphite thermal field
Graphite thermal field systems are mostly used in single crystal or polycrystalline thermal fields. Because the density, hardness, and compression resistance of isostatic graphite in the industry are better than other metal materials, it has the advantages of high temperature resistance, high pressure resistance, corrosion resistance, good conductivity, and stability. It is used in solar silicon wafer manufacturing. The importance of link graphite products is particularly prominent.
It is closely related to the development of the solar photovoltaic industry. At present, the quality of graphite products directly affects the quality of crystalline silicon drawing, and the quality of crystalline silicon has a direct relationship with the conversion efficiency of solar cells, so solar photovoltaic The quality of hot field graphite processing parts is the most important. There are more than 20 kinds of important graphite processing parts in an ordinary solar thermal field. For example, in the process of drawing single crystal silicon, the quality of the graphite crucible directly determines the number of times the crucible itself is used.
In the graphite thermal field system, there are many large and small graphite processing parts. Our common ones include graphite heaters, graphite crucibles, graphite trays, graphite upper, middle and lower insulation barrels, graphite guard plates, graphite electrodes, graphite shafts, graphite electrode covers, Graphite fasteners and so on, of course these are just some of them.
Solar energy is a reproducible clean energy. Monocrystalline silicon and polycrystalline silicon are the material basis for photoelectric conversion. Therefore, the graphite processing parts of solar photovoltaic thermal field will also get more rapid development.
