product_detail
When sintering high-value electronic and semiconductor materials, users have strict requirements for purity, dimensional stability and consistency. Isostatic graphite sagger is the preferred solution, far outperforming conventional extruded graphite saggers in precision thermal processes. Dongguan Jiecheng Graphite fabricates isostatic graphite saggers for high-standard sintering applications.
Core Product Features
Isostatic graphite is isotropic, meaning its mechanical and thermal properties remain consistent along X, Y and Z axes. It has excellent edge retention, and sharp corners and thin walls are less likely to chip during CNC machining and thermal cycling. Ultra-fine grain structure delivers low ash content and low outgassing, meeting strict cleanliness standards for semiconductor and electronic materials. It maintains good flatness after hundreds of heating cycles and is not prone to warping. The material also shows balanced thermal shock resistance, suitable for furnaces with fast heating and cooling curves.
Main Application Scenarios
- Semiconductor ceramic component and ceramic packaging sintering
- High-performance sputtering target sintering
- Precious metal powder and noble alloy sintering
- Special electronic functional material sintering
- Laboratory high-precision thermal treatment and material research
Isostatic graphite sagger is recommended if contamination tolerance is extremely low, and you require stable tolerance over long runs. At Jiecheng Graphite, our 5-axis CNC workshop handles complex custom structures. We provide property certificates and full dimensional inspection before shipment for global customers.
