Graphite Hot Zone for Poly-silicon Production

XRD Graphite specializes in the production of graphite hot zone, graphite rotors, graphite crucibles, graphite boats, graphite tubes, graphite rods, graphite baffles, graphite flow channels, graphite plates, etc.XRD Graphite's own special graphite production line can provide more than one hundred different specifications of graphite raw materials. According to the needs of different industries for different graphite materials, select specific materials for customers, after special treatment such as oxidation resistance, effectively extend the life of graphite machining products, improve product cost performance.

Graphite hot zone introduction:

Graphite hot zone are mostly used in single crystal or polycrystalline thermal fields. Because the density, hardness and compression resistance of isostatic graphite in the industry are superior to other metal materials, it has the advantages of high temperature resistance, high pressure resistance, corrosion resistance, good electrical conductivity and stability. The importance of the graphite products is particularly prominent in solar wafers's production process.

At present, the quality of graphite products directly affects the quality of crystalline silicon, and the quality of crystalline silicon has a direct relationship with the efficiency of solar cell conversion. Therefore, the quality of solar photovoltaic thermal field graphite machining parts must be guaranteed. 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. There are more than 20 kinds of important graphite parts in an ordinary solar thermal field. Commonly used are graphite heaters, graphite crucibles, graphite trays, graphite insulation barrels, graphite trays, graphite electrodes, graphite shafts, graphite electrode sleeves, Graphite fasteners, etc.

Advantages of XRD Graphite's Graphite Hot Zone:

●Material selection: using special graphite developed by XRD Graphite as raw material, high purity, high strength, high hardness, oxidation resistance, low porosity, abrasion resistance and the thermal conductivity is significantly better than other crucibles.

●Product processing: High-precision processing in strict accordance with customer's drawings. After installation, the components are closely matched and have high concentricity, effectively avoiding mechanical stress damage.

●Coating resistance:The exterior has a special glaze layer and a dense molding material, which greatly improves the corrosion resistance of the product and prolongs its service life.

XRD Graphite focus on supply large quantities of stable quality graphite products to customers with graphitization or graphite machining needs. To date, XRD Graphite has forged lasting relationships with key customers in over 30 countries and be considered as one of the leading supplier of graphite manufacturing and machining products in China. XRD Graphite is to constantly provide superior customer service while delivering stable quality graphite products in mass production.
