High Temperature 1700C Three Zone Tube Furnace with Alumina Tube 50mm 60mm 80mm OD for Material Research and Industrial Heat Treatment

Product Overview

This high-temperature three-zone tube furnace represents a pinnacle of thermal engineering, designed specifically to meet the rigorous demands of material science research and advanced industrial production. By utilizing a sophisticated triple-zone heating configuration, the system provides unparalleled control over thermal gradients, allowing researchers to establish extremely stable constant temperature zones or precise temperature slopes. This equipment is the primary choice for processes requiring sustained high-temperature operations up to 1700°C under controlled atmospheric conditions, ensuring that sensitive materials are treated with the highest degree of repeatability.

Targeted at sectors such as semiconductor manufacturing, aerospace metallurgy, and technical ceramic development, the unit excels in applications ranging from Chemical Vapor Deposition (CVD) to the annealing of specialized alloys. The core value proposition of this system lies in its ability to manage complex thermal profiles that single-zone furnaces simply cannot achieve. By integrating high-purity alumina components with advanced molybdenum disilicide (MoSi2) heating elements, the equipment ensures a clean, contaminant-free processing environment, which is critical for the integrity of high-purity R&D samples.

Reliability is engineered into every component of this thermal processing system. From the double-layer steel housing that maintains a cool exterior even during peak operation to the precision-calibrated Type B thermocouples, the unit is built for long-term consistency in demanding laboratory and pilot-scale industrial environments. Procurement teams can invest with confidence, knowing this system provides a robust platform for sensitive heat treatment processes where thermal precision is non-negotiable and operational uptime is essential for project success.

Key Features

• Independently Controlled Three-Zone Heating: The furnace architecture features three distinct heating zones (Left: 195 mm, Middle: 220 mm, Right: 195 mm) each governed by its own PID controller. This setup allows for the creation of an extended uniform temperature zone of 300 mm at 1600°C, or the establishment of specific thermal gradients required for crystal growth and specialized vapor transport processes.
• High-Purity Alumina Processing Tubes: Buyers can select from 50mm, 60mm, or 80mm OD alumina tubes, all 1200mm in length. These high-density ceramic tubes offer exceptional thermal shock resistance and chemical inertness, preventing sample contamination even at the maximum operating threshold of 1700°C.
• Advanced Molybdenum Disilicide (MoSi2) Elements: Featuring 14 high-grade MoSi2 heating elements, the system achieves rapid ramp rates and long-term stability. At high temperatures, these elements form a protective quartz coating that prevents further oxidation, ensuring a long service life and consistent power output across thousands of heating cycles.
• Precision Atmosphere and Vacuum Control: The system is equipped with water-cooled stainless steel flanges featuring double silicone O-rings. This hermetic sealing allows for reliable operation under high vacuum or controlled gas environments, supported by integrated KF25 ports and a needle valve for gas management.
• Superior Thermal Insulation: Utilizing high-quality fibrous alumina thermal blocks and a double-shell steel case, the equipment minimizes heat loss. This focus on insulation efficiency not only reduces energy consumption but also ensures the furnace surface remains at a safe touch-temperature below 70°C.
• Intelligent PID Programming: The control interface supports 30 programmable segments for heating, dwelling, and cooling. This level of granularity enables complex heat treatment recipes to be executed automatically, with built-in protections for overheating and thermocouple failure, ensuring process safety and repeatability.
• Enhanced Water Cooling System: To protect the structural integrity of the vacuum seals and flanges during ultra-high temperature runs, the system features integrated water-cooling ports. This ensures the seals remain within their operating temperature range, maintaining vacuum integrity even during 1700°C processing.
• Optional Digital Integration: The system can be upgraded with RS485 communication ports and Labview-based software. This allow for remote monitoring, recipe management, and comprehensive data logging via a laptop, which is essential for audit trails in regulated industrial R&D environments.
