1800C High Temperature Compact Vacuum Tube Furnace with 60mm OD Alumina Tube and Kanthal MoSi2 Heating Elements

Product Overview

This high-temperature thermal processing system is engineered for specialized material and chemical research laboratories requiring extreme thermal environments. By combining a compact footprint with industrial-grade heating capabilities, the equipment allows researchers to achieve temperatures up to 1800°C within a controlled vacuum or inert gas atmosphere. The system is fundamentally designed to facilitate the sintering of advanced materials, ceramic synthesis, and high-temperature purification processes that demand both precision and reliability. Its architecture emphasizes energy efficiency and rapid thermal response, ensuring that laboratory throughput is maximized without compromising the integrity of delicate samples.

Targeting industries ranging from aerospace and semiconductor manufacturing to advanced metallurgy and solid-state chemistry, this unit provides a versatile platform for exploring the thermal boundaries of new material samples. The integration of high-purity refractory materials and Swedish-engineered heating components ensures that the system maintains a clean processing environment, which is critical for preventing cross-contamination during sensitive R&D cycles. By providing a stable and repeatable thermal profile, the equipment empowers engineers to transition from experimental theory to verifiable results with high confidence in the data produced.

Built for demanding industrial and academic environments, the system features a robust double-layer steel casing that prioritizes operator safety and equipment longevity. The focus on durability is evident in the selection of a high-purity alumina refractory chamber reinforced with a zirconia liner, which provides superior resistance to thermal shock and chemical erosion at peak temperatures. This unit represents a convergence of high-end thermal engineering and practical laboratory utility, offering a dependable solution for the most challenging heat treatment applications in modern material science.

Key Features

• Kanthal Super-1900 Grade MoSi2 Heating Elements: Equipped with four premium Swedish-made Molybdenum Disilicide elements, this furnace achieves exceptional temperature uniformity and longevity even when operating at the upper limits of its 1800°C range. These elements are renowned for their ability to form a protective quartz layer that prevents further oxidation, ensuring consistent performance over thousands of hours.

• Advanced YSZ Ceramic Liner: The high-purity alumina refractory chamber is enhanced with a 15mm 2500°C grade Yttria-Stabilized Zirconia (YSZ) liner. This multi-layered insulation strategy maximizes energy retention and protects the structural integrity of the furnace chamber from the intense radiant heat generated during high-temperature cycles.

• Precision SCR Digital Control System: Temperature regulation is managed via a high-precision Silicon Controlled Rectifier (SCR) digital controller. This system supports a 30-segment programmable profile, allowing for meticulous control over ramping, soaking, and cooling rates with a remarkable accuracy of ±1ºC, ensuring repeatable results for complex sintering protocols.

• Integrated Vacuum and Gas Handling: The system includes a pair of stainless steel sealing flanges with double silicone O-rings, needle valves, and a dial vacuum gauge. This integrated setup allows for immediate operation under vacuum or controlled atmospheric conditions, with the capability to reach vacuum levels as deep as 10^-5 torr when paired with a molecular pump.

• Ultra-High Purity Alumina Processing Tube: The equipment utilizes a premier-grade alumina tube manufactured in the USA, featuring a 60mm outer diameter and 99.9% purity. This high-density ceramic vessel provides a chemically inert environment for sample processing, preventing contamination and withstanding extreme thermal gradients.

• Superior Energy Efficiency: Engineered for low power consumption, the furnace requires less than 1600W to maintain a stable 1800°C environment. This efficiency reduces operational costs and minimizes the heat load on laboratory HVAC systems, making it an eco-friendly choice for sustainable research facilities.

• Enhanced Safety Casing: The double-layer steel casing is equipped with two internal cooling fans, ensuring the external surface temperature remains below 60ºC even during maximum heat operations. This passive and active cooling design protects laboratory personnel and adjacent equipment from accidental heat exposure.

• Eurotherm 3000 Series Controller Compatibility: For users requiring advanced data management, the system is compatible with Eurotherm programmable controllers and iTools software. This allows for digital recipe management, real-time temperature tracking via laptop, and detailed logging of thermal cycles for quality assurance and regulatory compliance.

• High-Temperature Fiber Tube Blocks: To prevent heat radiation from damaging the sealing flanges and to improve temperature uniformity in the center of the tube, the system includes four fibrous ceramic tube blocks. These blocks are essential for maintaining the thermal integrity of the 125mm heating zone.

• Rigid Compliance and Certification: The standard configuration is CE Certified, ensuring it meets rigorous European safety and performance standards. For North American laboratories, NRTL (UL61010) or CSA certifications are available as optional upgrades to meet specific institutional safety requirements.
