Product Overview






This high-temperature graphitization system represents the pinnacle of thermal engineering for advanced material science. Specifically designed to reach operating temperatures up to 2800°C, the equipment utilizes premium graphite heating elements and multi-layer graphite felt insulation to achieve the extreme thermal environments required for the graphitization of carbon-based materials. Housed within a double-walled, water-cooled stainless steel 304 vacuum chamber, the system provides a stable and controlled atmosphere, capable of maintaining high vacuum levels or operating under inert gas environments. The integration of a motorized bottom-loading sample stage ensures seamless handling of delicate specimens, making it an essential tool for high-end research and development.
Targeted primarily at industries involved in carbon-carbon composites, synthetic graphite production, and battery electrode material development, this unit provides the precise thermal trajectories necessary for structural transformation at the molecular level. Whether utilized in aerospace engineering for heat shield testing or in the semiconductor industry for high-purity thermal processing, the system delivers consistent, repeatable results. The robust construction and advanced material selection allow it to withstand the rigors of continuous high-temperature operation, providing researchers with a dependable platform for exploring the frontiers of material science.
Reliability is at the core of this thermal processing solution. By employing a dual-input temperature control strategy—utilizing C-type thermocouples for low-range accuracy and sophisticated dual-color pyrometers for ultra-high temperature monitoring—the equipment maintains exceptional stability and uniformity. Safety is prioritized through a comprehensive array of interlocks governing water flow, pressure, and temperature thresholds. This meticulous attention to engineering detail ensures that the system performs under the most demanding industrial R&D conditions, offering peace of mind to procurement teams and laboratory managers alike.
Key Features
- Ultra-High Temperature Capability: The system is engineered to reach and sustain temperatures up to 2800°C, powered by high-purity cylindrical graphite heaters that ensure efficient and uniform radiant heat transfer throughout the effective heating zone.
- Precision Dual-Input Control: Featuring a Eurotherm 3000 series controller, the unit employs a 28-segment programmable PID loop that automatically transitions between a C-type thermocouple (RT to 1300°C) and a dual-color pyrometer (1300°C to 2800°C) for seamless and accurate temperature management.
- Advanced Vacuum Architecture: The water-cooled stainless steel 304 chamber is designed for high-vacuum integrity, achieving pressures lower than 5e-3 torr after bakeout, which is critical for preventing oxidation during sensitive graphitization processes.
- Motorized Bottom-Loading Design: To facilitate easy sample handling and minimize the risk of damage to the internal heating elements or insulation, the furnace utilizes a motorized bottom-loading sample stage that provides smooth vertical movement for loading and retrieval.
- Sophisticated Thermal Insulation: The interior is lined with three to five layers of high-density graphite felt, which provides superior thermal shielding, minimizes heat loss to the chamber walls, and contributes to a temperature uniformity of less than ±8°C.
- Comprehensive Safety Interlock System: Integrated sensors continuously monitor water flow, water pressure, and over-temperature conditions, automatically triggering safety protocols to protect both the operator and the equipment in the event of a utility failure.
- Versatile Gas Compatibility: The system is configured to operate under various atmospheric conditions, including high-purity Argon for the full temperature range, or specialized gas mixtures like Hydrogen, Methane, or Ammonia at specific temperature intervals for specialized chemical vapor processes.
- High-Performance Pressure Monitoring: Equipped with an Inficon Pirani capacitance diaphragm pressure gauge, the unit offers precise measurement from 3.8E-5 to 1125 Torr, allowing for exacting control over the internal environment during different stages of the heat treatment cycle.
- Robust Water-Cooling Infrastructure: Both the stainless steel chamber and the graphite electrode feedthroughs are water-cooled to ensure the exterior remains safe to touch and the electrical connections remain stable even when the core exceeds 2500°C.
