High Temperature Split Tube Furnace 1500C for Material Research Vacuum and Atmosphere Thermal Processing

Product Overview

This high-performance split tube furnace represents the pinnacle of thermal processing technology for material science and industrial R&D. Engineered to reach peak temperatures of 1500℃, the system utilizes high-grade silicon carbide heating elements and advanced insulation to provide a stable, controlled environment for sensitive chemical and physical transformations. The horizontal split-hinge design allows for unparalleled access to the processing tube, facilitating the integration of complex experimental setups and rapid sample retrieval without compromising the structural integrity of the furnace tube or the internal heating environment.

Designed specifically for universities, research institutes, and demanding industrial laboratories, the equipment excels in multi-phase thermal treatments including vacuum annealing, chemical vapor deposition (CVD), and atmosphere-controlled sintering. By combining a double-shell structure with integrated fan cooling, the unit maintains a safe, low exterior surface temperature even during prolonged high-heat cycles. This balance of power, accessibility, and safety makes it an essential tool for engineers and scientists pushing the boundaries of metallurgy, semiconductor development, and advanced ceramics.

Reliability is at the core of this system's architecture. Every component, from the high-purity corundum tube to the stainless steel vacuum flanges, is selected for its ability to withstand the stresses of rapid thermal cycling and aggressive chemical atmospheres. Whether performing routine heat treatments or complex catalytic graphitization, this thermal processing unit delivers the repeatability and precision required for high-stakes industrial and scientific applications, ensuring consistent results across every batch.

Key Features

• Precision Split-Hinge Architecture: The furnace chamber is designed with a heavy-duty hinge mechanism that allows the top half of the heating zone to be opened. This provides direct access to the process tube, simplifying the placement of catalysts, substrates, and thermocouples while allowing for much faster cooling rates when required by specific experimental protocols.
• Advanced Silicon Carbide (SiC) Heating Elements: Utilizing premium SiC rods, the system achieves rapid temperature ramp rates of up to 10℃ per minute. These elements are chosen for their exceptional resistance to oxidation and long-term stability at high temperatures, ensuring a consistent thermal output over thousands of operational hours.
• High-Efficiency Polycrystalline Alumina Insulation: The chamber is lined with 1800-grade polycrystalline alumina fiber featuring a specialized reflective coating. This design significantly reduces heat loss through the walls, improving energy efficiency by up to 30% compared to traditional firebrick insulation and maintaining superior temperature uniformity within the process zone.
• Intelligent PID Temperature Management: The system is equipped with a sophisticated 30-segment programmable PID controller. This allows users to define complex heating, dwelling, and cooling ramps with a high degree of precision, featuring auto-tune functions, over-temperature alarms, and thermocouple failure protection to safeguard both the equipment and the samples.
• Comprehensive Vacuum and Atmosphere Control: Engineered for versatile gas environments, the unit includes dual-ended stainless steel flanges with integrated needle valves, pressure gauges, and air cocks. With the optional high-performance vacuum pump systems, internal vacuum levels can reach 10-3 Pa, enabling clean, oxygen-free processing.
• Phase-Shift Triggered Power Supply: To ensure smooth and stable power delivery to the heating elements, the system employs a German-engineered Semikron phase-shift trigger and silicon-controlled rectifier. This provides a soft-start capability that extends the lifespan of the heating elements by preventing current surges.
• Integrated Safety Interlocks: Safety is prioritized through an automatic open-cover protection system that immediately cuts power to the heating elements when the furnace is opened. This prevents electrical hazards and protects the operator from accidental exposure to energized components during sample handling.
• Robust Dual-Shell Construction: The external housing is constructed with a dual-layer steel shell that incorporates a forced-air cooling system. This engineering choice ensures the exterior surface remains below 45℃, protecting lab personnel and preventing heat interference with surrounding sensitive analytical equipment.
