1700℃ Laboratory High Temperature Tube Furnace with Alumina Tube

Introduction

The 1700°C Alumina Tube Furnace is a specialized laboratory instrument engineered for extreme high-temperature applications. It is widely used in research and industrial settings for advanced processes such as nanomaterial synthesis, chemical vapor deposition (CVD), vacuum sintering, and precision heat treatment. The system features a high-purity alumina ceramic tube as the central reaction chamber, which provides superior thermal stability and excellent resistance to acids and alkalis. This model is powered by high-performance Molybdenum Disilicide (MoSi₂) heating elements arranged around the tube.

Tube furnaces offer several advantages, including compact design, precise temperature control, and a relatively small workspace. They are particularly suitable for applications requiring precise temperature regulation and a clean, inert environment. The alumina tube's high purity and thermal stability make it ideal for high-temperature processes, ensuring minimal contamination and extended service life.

Applications

The 1700°C Tube Furnace is specifically engineered for critical processes requiring extreme heat and strict atmosphere control. It is the preferred instrument for:

• Advanced Ceramics & Refractory Research (Core Application): Essential for the sintering and densification of high-melting-point ceramics such as Zirconia (ZrO₂), Alumina (Al₂O₃), and Silicon Carbide (SiC). It is also ideal for testing the thermal shock resistance of refractory materials used in aerospace and heavy industry.
• Semiconductor & Crystal Growth: Widely used in the annealing of Silicon Carbide (SiC) wafers, crystal growth of wide-bandgap semiconductors, and high-temperature doping processes that demand temperatures exceeding 1400°C.
• Powder Metallurgy & Superalloys: Enables the sintering of Tungsten (W), Molybdenum (Mo), and other refractory metals. It plays a key role in the development of superalloys and high-entropy alloys for turbine blades and aerospace components.
• Advanced Nanomaterial Synthesis: Provides the extreme thermal energy required for the CVD growth of carbon nanotubes, graphene, and nanowires, as well as the synthesis of high-purity ceramic powders.
• Materials Testing at Extreme Temperatures: Used for studying phase diagrams, melting points, and material behavior (creep, fatigue) under extreme thermal conditions up to 1700°C.

Detail & Parts

Principle

The 1700°C Alumina Tube Furnace utilizes Molybdenum Disilicide (MoSi₂) as its core heating elements. Upon activation, electrical energy is converted into thermal energy and transferred to the high-purity alumina tube reaction chamber via thermal radiation and conduction. Managed by an intelligent PID control system that monitors and adjusts temperature in real-time, the furnace establishes a stable and controllable high-temperature environment, meeting the needs of the most rigorous experimental applications.

Features

Tube furnaces with alumina tubes are ideal for applications requiring relatively small workspaces and features such as multiple zones, independently controlled. Alumina tubes are required for high-temperature operation, but they are subject to thermal shock. The smaller the diameter of the process tube, the better. KINTEK manufactures tube furnaces for operating temperatures up to 2000 degrees centigrade. In addition to vertical and horizontal tube models, we offer a bottom-loading vertical tube and combination units that allow the tube to be placed either vertically or horizontally. Water-cooled end caps and gas mixing systems are optional.

Warnings

Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
