As a leading supplier of customized graphite crucibles in China, VeTek Semiconductor mainly provides Isostatic Graphite Crucible, SiC Coated Graphite Crucible Deflector, Glassy Carbon Coated Graphite Crucible, etc. Our graphite crucibles are made of high-purity graphite raw materials and manufactured through precision technology, with excellent high temperature resistance, corrosion resistance and thermal conductivity. Welcome to consult us.
VeTek semiconductor Isostatic Graphite Crucible is typically crafted from high-purity graphite materials. These graphites are engineered to exhibit exceptional thermal stability, resistance to chemical corrosion, and thermal expansion properties.VeTek semiconductor Isostatic Graphite Crucible composition ensures it can withstand the extreme conditions encountered during high-temperature processing.
Isostatic Graphite Crucible is precision-engineered to withstand the demanding conditions of semiconductor manufacturing processes. They feature a robust, cylindrical shape with a smooth interior surface to facilitate uniform heat distribution and crystal growth. The design of VeTek semiconductor Isostatic Graphite Crucible minimizes the risk of impurities contaminating the semiconductor material during processing.
Meanwhile, our three-petal Graphite Crucible possess excellent thermal conductivity, enabling efficient heat transfer during the crystallization process. This property ensures consistent temperature distribution within the crucible, promoting uniform crystal growth and minimizing thermal gradients that could compromise product quality.
Besides,Isostatic Graphite Crucibles find widespread use in various semiconductor manufacturing processes, including the growth of monocrystalline silicon ingots via techniques such as Czochralski and float-zone methods. These Crystal growth graphite crucibles provide a stable and controlled environment for the precise formation of semiconductor Crystal growth, crucial for producing high-quality materials used in electronic devices.
