Vacuum furnace graphite crucible
Jincheng Graphite, as a professional manufacturer of graphite products, provides high-purity vacuum furnace graphite crucibles, specially designed for high-temperature vacuum processes. The products have advantages such as high temperature resistance, uniform heat conduction, energy saving and high efficiency, and are widely used in semiconductor, new energy and other fields.
Core Advantage
Material and Process Innovation
Utilizing natural graphite precision processing technology in conjunction with low-temperature sintering process, the crucible can maintain structural stability at a temperature of 2500℃, preventing cracks or deformations caused by thermal expansion and contraction. The surface nano-coating technology enhances thermal conductivity, reduces energy consumption, and simultaneously enhances oxidation resistance.
Precise Temperature Control Performance
The vacuum furnace graphite crucible adopts a multi-layer composite structure design to achieve uniform heat distribution, avoiding material ablation caused by local overheating. Combined with an intelligent temperature control system, it can precisely control temperature fluctuations within ±2℃, meeting the high-precision process requirements such as semiconductor wafer sintering and battery electrode sheet drying.
Customization and Adaptability
Jin Cheng Graphite provides a full-process service from design to production, supporting the customization of crucible size, power distribution, and vacuum sealing structure according to customer drawings. It is compatible with global mainstream vacuum furnace equipment and can meet high-temperature and high-vacuum application scenarios in complex conditions.
Application Scenario
Vacuum furnace graphite crucibles are widely used in semiconductor wafer sintering, drying of new energy battery electrode sheets, and vacuum heat treatment of aerospace materials, etc. Their high thermal conductivity enables rapid and uniform heating of the workpiece, while their high-temperature resistance ensures stable operation in extreme environments. In a vacuum environment, the sealing performance and anti-corrosion ability of the crucible are significantly superior to traditional materials, making it a core component for high-temperature and high-vacuum processes.
