product description

In the semiconductor manufacturing process, its equipment needs to operate for a long time at a high temperature of more than 1200°C. High pure graphite sleeve can not only withstand extreme stress, but also avoid metal impurities from contaminating wafers. Compared with other materials, high-purity graphite sleeves have stronger thermal shock resistance, extend service life, and reduce equipment maintenance frequency.

When high pure graphite sleeve is used in photovoltaic single crystal silicon furnaces, their directional heat conduction characteristics help to accurately control the temperature gradient of silicon melt, thereby ensuring the axial production rate of single crystal silicon rods and reducing the defect rate of silicon crystals.

High pure graphite sleeve is also important components in the metallurgical field, such as their application in titanium alloy vacuum melting furnaces. Its chemical inertness avoids melt contamination; its excellent self-lubricating property enables the rotating mechanism to run smoothly under oil-free lubrication conditions, ensuring uniform melt composition. Compared with ceramic bushings, graphite sleeves have stronger thermal shock resistance.

The reason why many industrial fields choose to use high pure graphite sleeve is mainly due to its high strength, low thermal expansion coefficient, chemical inertness and electrical conductivity. These characteristics work together to meet the stringent requirements of modern industry for precision thermal equipment.
