High Temperature 1700C Tube Furnace with 4 Inch OD Alumina Tube and Vacuum Sealing Flanges

Product Overview

This high-temperature bench-top furnace system provides a versatile and robust solution for material science and chemical research laboratories requiring extreme thermal processing up to 1700ºC. Designed for precision and stability, the equipment is engineered to facilitate the sintering of advanced material samples under varied atmospheric conditions, including high vacuum and inert gas environments. The compact footprint and high-performance heating profile make it an essential tool for institutional and industrial RD centers focusing on ceramics, metallurgy, and semiconductor development.

Primary use cases for the system involve precisely controlled heat treatments where atmosphere purity is critical. By integrating high-purity alumina processing tubes with sophisticated sealing assemblies, this unit allows researchers to explore phase transformations, crystal growth, and chemical vapor deposition processes. The furnace's architecture is optimized for rapid thermal cycling and long-term temperature maintenance, ensuring that demanding experimental protocols are executed with repeatable accuracy.

Reliability is at the core of this thermal processing unit's design. Utilizing a double-layer steel casing with advanced air-cooling technology, the equipment maintains a safe touch-temperature even during peak operation. The integration of 1800-grade Molybdenum Disilicide (MoSi2) heating elements ensures longevity and consistent performance under high-temperature loads. Procurement teams can be confident in the system’s industrial-grade components and its ability to withstand the rigors of continuous high-heat scientific inquiry.

Key Features

• Advanced 1800-Grade MoSi2 Heating Elements: The furnace utilizes eight high-specification Molybdenum Disilicide elements capable of withstanding temperatures beyond the system's operating limit, ensuring a large safety margin and extended component lifespan during 1700ºC cycles.
• Precision Alumina Refractory Chamber: The internal heating zone is lined with high-purity alumina fiber insulation, which minimizes heat loss, improves thermal uniformity, and prevents contamination of sensitive samples during processing.
• Dual-Layer Casing with Active Cooling: A heavy-duty steel outer shell with integrated cooling fans maintains the external surface temperature below 60ºC, protecting lab personnel and surrounding equipment while enhancing the longevity of internal electronics.
• Sophisticated PID Temperature Control: This system features a programmable digital controller providing ±1ºC accuracy. Users can configure up to 30 process segments for complex ramping, soaking, and cooling protocols, supported by phase-angle fired SCR power control.
• Integrated Vacuum Sealing Flange Kit: The equipment includes a complete stainless steel sealing assembly with a KF25 vacuum port and 1/4" gas pipe adaptors, enabling immediate transition between vacuum, inert gas, and ambient atmospheres.
• Safety Monitoring and Over-Temperature Protection: A built-in over-temperature alarm and automatic shut-off mechanism allow for unsupervised operation, providing peace of mind during long-duration sintering or annealing processes.
• High-Purity American-Made Alumina Tube: For the 100mm OD variant, the system incorporates a chemical-resistant alumina tube designed for superior thermal shock resistance and chemical inertness under extreme heat.
• Versatile Atmospheric Control: Utilizing two stainless steel needle valves and a dial vacuum gauge, the system provides granular control over gas input and vacuum levels, essential for sensitive chemical vapor deposition (CVD) workflows.
• Phase-Angle Fired SCR Technology: Unlike standard solid-state relays, the silicon-controlled rectifier (SCR) power control provides a smoother power delivery to the elements, reducing thermal stress and increasing temperature precision.
• Scalable Digital Communication: The unit is equipped with an RS485 communication port, allowing for PC-based monitoring and data logging, facilitating strict QC compliance and experimental documentation.
