We supply high quality molded graphite materials as blocks and rods, we select materials for customers based on our own experimental database. We are familiar with the characteristics of molded graphite materials at home and abroad, and provide more cost-effective products on the basis of
satisfying customer applications.
In the production process of quartz crucibles, it is most common to use the arc generated by the graphite electrode discharge to heat and melt the quartz crucible. Traditionally, three graphite electrodes are generally used as a group. Since the quartz crucible is an important accessory for solar and semiconductor single crystal silicon production, its purity requirements are relatively high, so the graphite electrode for quartz crucible must also be of high purity. We can supply graphite electrode and mold with purity less than 50ppm.
Materials suitable for graphite mold:
| We produce and supply processed graphite products for application of semiconductor industry. We have several CNC machining centers with high revolutions to ensure mechanical tolerance, and we have three coordinate measuring instruments, which can check the tolerance of processed work pieces to ensure the measurable quality. At the same, we have the state of the art purification furnaces, which can purify the processed products to ash content less than 2PPM. Product parameters of our material for graphite hot zone for semi-con
Product Description : Components used in semiconductor environment have high requirements for particle size. It not only needs to apply the good physical properties of graphite, such as high temperature resistance, corrosion resistance and plasma resistance, but also has high requirements for the purity and machining accuracy of graphite. We use imported purification equipment of international well-known brands, which can extract the purity of graphite processed parts to 5-50PPM, and the ash content of specially ordered products can be less than 2PPM. The main applications include graphite thermal field in semi-con single crystal furnace, including heating element, crucible, insulation cylinder, packaging fixture, etc. Basic production steps
